julien // alrighty so julien is such a romantic in so many ways, but especially in terms of relationships he's like so full of love? like he falls in love easily and very often and he's basically in love with love most of the time seeing as he's been in a lot of mediocre relationships and few pretty bad ones. out of the trio, he's got the most exes (the infamous eight evil exes), who i haven't really figured out exactly. i know when he was still in high school, he pretty much exclusively dated girls though he was definitely not under the impression that he was fully straight even at the time (i like to think julien and rhett were each other's first gay experience). and then there was the sr year and there was avery (and, arguably, pietro). and then there was mercy. and then that whole fiasco was over, and julien dated charlive, and some other guys and some other girls. and at the time, if you'd have asked him, he would've just been like "sexuality: ?????" because he never really identified as straight even before he started dating boys, but he just never really identified as anything? anyway, then he dated nolan and that ended in tears. i guess throughout this entire time, he and avery and tam are all banging on the regular because that's just where their relationship is at (and he loves them more than anyone, but if julien's looking for anything it's a relationship and commitment and he's definitely the marrying type of guy, whether that ends up being to a man or a woman or anyone). so i think at this point, julien is still trying to date audrina (mostly because scott pilgrim plot). and then he kind of figures out he identifies as pansexual and he's very comfortable in that identity because julien always fell in love with everyone really regardless of gender??
avery // so avery's always been sexually explorative and really took her sexuality into her own hands very early on, like she always kind of knew what she wanted and didn't really confuse sex and love, and all that. so basically she slept with guys whenever she felt like it and that was all well and good. and then there was pietro, who was the first person she ever actually fell in love with, like romantically (because the first person she fell in love with was definitely tam, but that was fully platonic). and then he died and that ruined her. and then she went back to more of the usual, and then there was james who was her second serious boyfriend, lasted three whole years before they broke up. (and then there was nico, but that's also very much platonic and avery doesn't consider him a boyfriend.) and then she started dating carsen, and that's kind of where things change? because avery was always definitely open to sex with girls but it was never something she really acted on (and in general, she's not very sexually attracted to girls. romantically is another story.) so she dates carsen, and they have an open relationship because avery's definitely more into fucking guys than girls. i'm not sure if she's still dating carsen or not, but either way, with avery there's a very distinct difference between sex and love and romance, and they don't always line up. because sexually, she's more or less straight, though she has had sex with girls from time to time (and she's very into making straight boys crossdress, so make of that what you will). romantically, i'd say she's biromantic. and then there's the whole queerplatonic thing where she definitely loves tam and julien and nico, but not from a romantic perspective even though sex is involved.
tam // right so tam was sort of a late bloomer compared julien and avery who started having sex at 16 and 15 respectively. tam has sex for the first time at 17 and it was with avery and it was pretty unorthodox, in that he wasn't in love with her or even like in lust with her, he was just her best friend and he trusted her completely and figured since she had a lot more experience she could kind of show him the ropes so that when he did want to do it with someone he wasn't a total mess. and that was that. he was very much the unpopular kid in high school, so it wasn't until college that he was getting ass left right and center. (and by then it was all under the influence of booze and/or drugs so he wasn't nervous about flirting and asking people out and all that.) on a sort of similar not to julien, tam had never really thought about who he was attracted to in high school (mostly because he wasn't attracted to anyone really) and then in college it was just anyone and everyone. he never really had any serious relationships either, except jean-luc and arguably carsen. for him it's mostly just avery and julien now, and again it's more of a trust thing than it is romance. i guess tam was always okay with all genders, which kind of brings me to the topic of his gender. i never really considered it, but in hindsight i can see him not really identifying as male or female, but he's not agender either. like he's really just, gender: ????? he doesn't really give a shit about pronouns, he/him is fine with him because he's used to it what with being dmab. i guess he's more accurately postgender anyway.
