I strongly believe that Katakuri is actually experienced with sex but not with kissing or relationships. Like he got his experience from hooking up with many prostitutes, and no one can say no to someone of his status as a minister and a sweet commander, besides HAVE YOU SEEN HIM?!!! And you’d think that these hookers would make the smart move and actually try and have his child. Well, let me tell ya, YOU’R WRONG! everyone is scared of him and of what he and Mama would do, since everyone know how important marriage is to the Charlottes. So basically no one would try and screw with them. Just get in there, get the job done, get payed, and dISAPPeAr!!!
I also believe that one of his biggest turn ons are actual kisses, like kissing on the lips. Because he never got to do that because of his mouth. So when he finally gets to kiss his s/o, instant hard rock! And as Bas said when answering my ask (which I’m really grateful for and so happy with the outcome!) he gets super turned on by neck and ears kisses, since those parts are usually covered with his scarf. I also headcanon him as having VERY sensitive jaw, chin, nipples and shoulders. Again it has to do with them being covered most of the time.
Also he likes to hold his s/o’s hand when getting intimate, it just makes him feel this warmth explodes in his chest and he just feels so safe while holding her hand (even though it will basically disappear in his own huge hand but still, he feels safe like that!) another thing that makes him feel safe is cuddling. And his favorite thing to do is sneaking on his s/o when she’s chilling on the bed/couch and just crawl between her legs and rest his head on her stomach/chest with her legs wrapped around his abdomen. Another favorite cuddling position? Is when she’s lying on her side while holding his head against her chest with his arms around her waist as he nuzzle between her breasts ok I’m done bye!
