Which are you saying why not to?
If it’s why I won’t date a mean is because I won’t put myself in a situation with someone who is willing to negatively insult my appearance. (Let’s say they are a rude Looksmaxxer) I doubt it would affect me, but it is still the principle/morality. I also wouldn’t be comfortable with the way he speaks about others. No matter how attractive someone is, if I find out they’re a bad person *I* lose attraction.
If you are asking why I cannot find myself dating someone, it’s because I just don’t like the idea of it. I don’t like physical touch and I cringe when people saying kind words. I’m also not good at receiving gifts either. It’d be bothersome.
