There is absolutely nothing wrong with being single. It can be quite fun, actually.
And guys think that if you don't have sex with them within 3 months, then you are prude and they may dump you. That's a negative. If that was the case, I wouldn't be with my boyfriend whom I've been dating for over a year because it took about 7 and a half months before I was ready to take that step. Did he think I was a prude? Absolutely not. How do I know? Because my boyfriend is extremely honest and blunt with me so he would have said something.
Well, I know for a fact that if a guy doesn't call you in a week it doesn't mean he doesn't want to, because dudes get confused about when they should... and I definitely know that you don't have to put out that soon, I know if a girl was eager to put out, that would just make me think she is a whore... and I am not saying that you have to be abstinent, but casual sex is just weird and pathetic...
