Uganda Forums: Where Ugandans Meet to Discuss Issues

I met a guy who became a close friend of mine. I later developed feelings for him but he made it clear that he did not want a relationship. I moved on and even got my self another guy but kept on communicating with him. We recently went out and had fun and while talking, i still made it clear, nothing more, i am with another guy. Later on, he wanted to have sex. I said no because i did not want to do anything with him. The only problem is that he got so angry and said i used him? Why don't men ever understand that when a woman says no, she really and honestly means no?
