I'm not sure Gojo has ever even shown an interest to any girls.
He calls Utahime weak and teases her by making fun of her, essentially- which she hates. Mei Mei is incredibly strong and beautiful, and Gojo acknowledges her skill but that's it. I also noticed that in the anime (the manga doesn't have honorifics, so please correct me if I'm wrong) but he calls her Mei-san rather than Mei Mei. Therefore, I don't think he ever tried to get much closer to her than the interactions we've seen. When she asks him if he'd comfort her if she cried, he tells her that's she strong- she wouldn't cry. I thought it was interesting that while Mei Mei's question was slightly flirty, Gojo answered so simply, without any teasing.
He calls Shoko by her first name, which is understandable since they spend more time together being in the same grade. He realizes that her ability is rare and useful, but like with Utahime and Mei Mei he doesn't go any further than that. He mostly speaks to her about work related things and doesn't flirt or tease much at all.
Honestly, I think Gojo actually respects his female colleagues and mostly pokes fun at Utahime because she's so uptight and strict. Shoko and Mei Mei are more relaxed and self-assured, and Gojo recognizes their skills and compliments them for it rather than teasing them. I doubt Gojo really thinks Utahime is truly weak more than he just loves riling her up. Other than that, Gojo's pretty respectful.
Also, in the Hidden Inventory arc, Gojo was bombarded with screaming from all the girls excited to see him. Other than pulling his shades down so they could see his face- after they asked him to, btw- he didn't really do much else. He didn't even react much to the teacher giving him her phone number. His only comment was "what a fun school," and it's interesting to see that while lots of girls do appreciate his looks, he acts only mildly amused.
Other than that one model as his wallpaper, we don't really see Gojo flirt or show interest with anyone. He only really teases Utahime to piss her off- I suspect he hates how much she follows the rules like Nanami does, who he teases often as well. He likely just enjoys annoying people so stern because rules just don't sit well with him (especially because of what those "rules" had done to Geto).
It's just a possibility, but he could be one of those guys who's more interested in work than pleasure- I know, he's handsome, but not all handsome people are players and cheaters. I think that's a horrible stigma and a lot of attractive people irl are judged and criticized solely for their looks. People make too many assumptions on someone just based on their genes, and I think it's pretty shallow to think Gojo's a womanizer just because he's attractive. And he knows he's attractive- but when did being confident in yourself make you a philanderer? Gojo has never used his looks manipulatively at all.
It's definitely a possibility that he would be a womanizer, but I'd say it's unlikely based in what we've seen. To sum it all up, Gojo doesn't show interest in anyone. He teases Utahime often, likely for the same reason be teases Nanami- they're too uptight. Shoko and Mei Mei are both incredibly skilled and beautiful sorcerers, and he does acknowledge and compliment them for it, but he doesn't tease or flirt with them. He's respectful, and he works with them as his colleagues. He didn't get distracted by the teen girls fawning over him either, or suddenly get overtly cocky or show off, only sliding his glasses down so they could see his face, and even then he acted only mildly amused. Also, when Miwa asked him for a picture, he didn't even stay and chat with her or anything (I know she's a minor, but if he truly was a womanizer, he would have at least stayed to hear her compliment him or anything to feed his ego) Maybe ask her "Oh, you want a picture with me? The strongest? How cute~" A flirty comment, a joke, something to fuel his own ego, but he doesn't do that. He doesn't act in a way that conveys he openly pursues attention from women. He just takes the picture with her and walks off casually.
Therefore, other than the fact that he's handsome- and I know many people who would assume things about someone based on their attractiveness, which is a terrible stereotype- Gojo doesn't show much interest in flirting at all. He could be the type of guy who works more than plays- and there's plenty of guys who are handsome but aren't super interested in playing around. Being handsome doesn't automatically mean he's the type to sneak around and have affairs here and there. It's completely realistic for a handsome man to be uninterested in any kind of relationships- not all men are sex crazed, and being a tease to his friends doesn't make Gojo a flirt either. Teasing your friends is perfectly normal.
Therefore, Gojo being a 28 year old virgin is totally possible- not everyone's a sex crazed teen who only thinks about what's between their legs, and basing it on what normal Japanese teens do is unfair. Neither Gojo or his lifestyle is exactly normal, and there's definitely barriers when it comes to experiencing normal youth activities for Gojo's generation- especially Gojo's generation. Yuji's generation definitely has more freedom to do fun things because of what Gojo has done to give the youth more freedom- things he hasn't been able to experience himself in his youth, like playing baseball during the exchange event. That was the first time they ever did something different to tradition, and that was only because of Gojo's consideration.
Gojo's youth was filled with blood, exorcising, and choosing between life and death. The deaths Yuji and co. witnessed were what Gojo experienced as well, if not worse. Gojo's task in his youth was to protect the weak, and he found that burdensome. At least, until Geto betrayed them, and Gojo realized the new burden he had to bear in changing the Jujutsu world because of what it had done to his only best friend.
There are definitely more important things in Gojo's mind than just losing his virginity, like saving people and choosing who to save, whether he should kill or not kill.
Gojo is the strongest, but he also bears the biggest burden- and that burden is something he chose to bear, and being the strongest is something he chose to be. Because before Geto left, it was "We are the Strongest." Now, Gojo worked tirelessly so that he could say "I am the Strongest."
And that's not something you can do while sleeping around. I think a lot of people fail to recognize just how hard Gojo works for himself and others. They just think, oh he's the strongest, so it should be easy for him. But it's really, really not that simple, is it? Especially when you have to do it on your own, and even then Gojo realizes that his strength alone isn't enough to save people. He can't save everyone by himself- It's not enough for just him to be the Strongest, so he works diligently to build and inspire his students to stand with him.
He's actually a very deep and emotional man who cares about his students and especially, even now, his best friend. Everything he does is for their sake- he sacrifices the normal life he could have lived, like Nanami had done, for their sake. And he fights with the higher ups, takes the brunt of their ire, and laughs it off, acting as if he fine, like a dad pretending he's superman for his kid's sake. But Gojo is burdened, and he's tired, and he hardly sleeps, and he has the most missions- he's the Strongest, which means everyone needs him, and he bears it.
Sorry for ranting again tho. I think I went into two different topics lol oops- 🤔
OUR SAVIOR 🤔 EDUCATING PEOPLE pay attention ya'll another thing I've noticed in the latest episode is that in his phone contacts he actually writes Utahime's name properly like formally no emojis or teasing shit he actually sees them as his colleagues people he can rely on his field of work and yes about the whole thing when he bursted into riko's class man was absolutely clueless just silent as a teacher tries to give him his number. I'm pretty sure as a child Gojo wasn't allowed to attend public schools due him being in danger or putting others in danger so he doesn't know much about public schools or normal people in general since he spends all his time with people from the jujutsu society.
That is definitely true just because someone is good looking that doesnt mean he's some cheap womanizer. I see a lot of people shipping him and Utahime together which is understandable ship who you like but I don't think Gojo as any ulterior motives like wooing Utahime by teasing her he just is plainly teasing ya know like friends do but in this case Utahime hates his guts and he doesnt know. I mean it takes some amount of hate to try to throw hot tea at someone 😂
While certainly I agree Gojo's teen like wasn't the best it was like he literally had a full time job at that age but who's to stay he didn't go messing around one time? I'm sure during his teen days he wanted to experience things he didnt get to to but now could because he lives on his own now. But maybe he didnt at all who knows? Which also raises another question, I wonder if he has any romantic experiences? And this was all before what happened in the hidden inventory arc after that I can see him more becoming invested in his duty and with what happened with geto as well would of definitely had a huge impact on him to try harder even though hes the strongest so that the next generation wouldn't have to experience the things he went through.
It's really sad if you really think about it what hes been through and what he has to shoulder all while keeping the facade that he's okay, I bet there were times he cursed his powers and his life....but he bears with it anyways because everyone is counting on him....
And don't be sorry at all! I am actually really learning alot about Gojo from you. Please continue to tell us your thoughts and feelings. I don't mind at all ❤ and thank you for taking the time to write 💕
