Relationships that revolve around sex will never last. You must have more than that. That is why once sex comes into the picture things become more complicated. take the stories throughout this post. If you aren't strong enough without sex you will never be strong with it. That's why waiting to have sex will ensure that you are seeing the person for who they are and not what pleasures they give you. So many people stay with someone b/c the sex is good even if the girl/guy is a loser. Stop basing your relationships on sex and instead the things you have in common and how he treats you outside the bedroom and that's when you will know whether it's right.
