I used to be called cute routinely not only from girls, but from guys as well (strong no homo, srs, I swear), probably due to rounded, semi-feminine and baby potato face. Girls who were interested in me were mostly young BJs or they were from the same age max, I can't remember any older being anyhow attracted to me. The type of attraction I would say was purely emotional and there was virtually zero sexual appeal, but I can't say it was actually or only a platonic shit. Girls in majority usually let me to do anything from kissing, to touching, even fingering (yes EVEN), but I was rarely successful with actually getting p in v. I don't think the cause of the latter is my shitty social skills or inability of sealing the deal, because if she wants to fuk you, she'll take care of it and her intention will be clear in 1st place. Young, JBs and especially short girls appeared to be often attracted to me, not only as one girl in a group, but more - only conditions were usually shorter height and young age, after that it was 40:60 there will be some spark, that being emotional attraction or just some type of liking and it doesn't matter how good looking she was. It worked from 6 to strong 7 range, usually involving cute, feminine girls with baby faces, while hot girls weren't into me and ugly girls didn't bother with me at all, so it was good setup. It rarely happened that I'd be rejected from a group, because there was always one girl who let me in, bullying and ego feeding from girls was non existant and if it happened, other girls made that bitch shout. Often it happened that when I came into random group of girls, they all suddenly shut the fuck op and gave that lustful stare and got that big, puppy eyes. They were hugging and randomly touching me all the time. They talked to me all the time. I was receiving drink invitations, not sth to complain at. Even chads respected me, probably because I cawk blocked a few of them that I know, lol. For instance, A tall, dark and handsome brah, and girl just slipped out of his hug and she settled in front of me on the dance floor . Didn't even leave him phone number or suck dick.
Altough this may sound as some platonic, semi-friendzone saga, here and there there were some girls who acted very sexually around me. They were usually tall, somehow masculine girls and confident as fuck, I called them fetish girls and I was avoiding them.
Hopefully this random rambling confirms at least some of your theories.
