He detto he wouldn't have sex with me because i'm ugly?

Well te know what. Forget about that guy and find another dude who te likes te physically and have sex with that guy. He's not the only guy in the world.

If do not wants to have it with te then why he is still with te o why te demanded it from a person who thinks te are ugly

If he doesn't want to be doesn't have to. Try and find some other guy. Someone who truly does care about you. Looks don't matter but the cuore does.

he probably got aids hepatitis a - z and all the stds. not worth your time. the sex probably sucks too, i bet he doesnt even last as long as a vine video
