We're both 17. He is my EX's friend. As soon as he knew me and my EX broke up, he started talking to me. He keeps texting me and calling me to ask if he can come to see me at my house. But I think he just wants to have sex because he knew that me and my EX (his friend) had a sexual relationship. I keep making excuses to not see him because I don't want to have sex. I don't mind if it's just to hang out but I know he wants to just have sex because he's that type of selfish boy. What should I do? There's no way I would have sex with him. NO WAY. He must think I'm an easy sl*t...
