I had problems like this, a few girls were pulling my dick (literal translation of a phrase from my language). I'm 22, virgin (I only count girls, I'm BI and been with men, just have no sexual experience with girls), and it's not that bad. Until recently I lied to everyone because everyone assumed that I did it. A few weeks ago I just stopped lying. I don't mind telling that I'm a virgin to anyone anymore. Can't care less about their idiotic opinions.
There was this girls (still not sure if she likes me or not), she was a few times at my place (just cuddling the first time and hanging around), second time we both ended naked and horny, but she didn't want to do it. I didn't want to force her since I'm a gentle person, especially to girls even though she scratched and bit me all over. I didn't mind that for a second. I was confused for a while after she left, I was gentle, I made her rafaello, bought a drink (didn't want to get her drunk, just relaxed and naked), but she didn't want. Also, I didn't want to just have sex with her, I'd really like girlfriend.
But I'm not chasing after her. Because if I was able to get this far with a girl, I can do it again. + I'm a borderline sociopath, I have phases, strong ebbs and flows of interests. Right now I'd like to be locked up in a lab, devoid of any and all human contact (especially physical). It's not (just) because of her, it just happens. My friend told me to give her silent treatment, she told me not to contact her or anything for a few days. Still doing it... Pretty sure she doesn't like me as I thought she is.
My lack of experience makes me.... I think someone in this thread used a term clingy. I'd say that I fit that description. But lately since that girl didn't want to do anything with me, I stopped doing that. I'm even ignoring them, especially if they're "off the limits" (married or in relationship, even if interested in someone else). Why interfere in someone's affairs? It never brought me any good.
