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

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

If do not wants to have it with 당신 then why he is still with 당신 또는 why 당신 demanded it from a person who thinks 당신 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 심장 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
