Hi, I am 17 and a half years old and just graduated high school.. I have had sex with four girls all of which were good looking none of which were virgins. I have this mental problem I guess you could say where not only am I immediately a lot less attracted to a girl I meet once I found out they are not a virgin but if I know a girl whos been my friend (and most likely ive been trying to get with or gotten with) loses it thats all I could think about anytime I talk to them. I'm not an idiot, I know the common responses such as insecurities and such but I really do not believe it's that. Maybe someone has had a similar problem in their youth and figured it out hence why I post here. Thank you all for input!
