i have never experienced sex

im 16 and the last 2 years of my life i tried to change myself... i went the gym, i made loads of friends, i got a girlfriend. but nothing ever seemed to go the way i wanted it to. my new friends would never let me hang out with them, i used to be a fat kid and they would make fun of me constantly, i kept working out and i have the perfect body for my height and weight but i still have insecurities. i broke up with my ex girl because she never really wanted to have sex with me, she told me she was a virgin and it would be too soon for her... it felt really weird, i was naive back then, i knew nothing about girls, i was really ignorant, i thought she was just teasing me for being a virgin. we broke up and now everyone at school makes fun of me because my ex tells everyone i was begging her to have sex with me, she tells everyone that i pressured her to have sex. but i never. i dont know why she puts me through this, i dont know why she would say this when i never did that. she even put my name on a list called "the virgin list" and she put me number 1. i found out from one of my friends... its not really the threatening list as the name sounds, it just people she thinks will die a virgin. she is so mean to me, she is the only person i really liked, i dont know why she would do this to me. at this point, i would love to have sex with her just to spite her. she is perfect and all my friends think she is hot, she is my best friends sister and i know my best friend would never let me date her... but i dont want to anymore. i hate her so much, she is the only reason im insecure about anything. i hate it so much when people call me a virgin, im 16 and it makes me feel like those people think there is something wrong with me...
