You are having sex with them in order to make guys be interested in you? This is what I think, take as one of my opinion. If I were these guys, and could have sex with you easily. I would totally think this girl would do the same thing with another guy if she likes. If I get in a relationship with you, I’d be insecure that you may cheat. Even if you say you wouldn’t cheat, your actions make them think so. A guy who is really looking for true serious relationship with you won’t have sex with you that easily. For these guys, you are just one of easy girls who gives her body, even if a boy came to you. Mostly, it’s not because he likes you. I guess it’s because he just wants your body. You shouldn’t give your body to someone that easily if you are seriously looking for true one. This is my opinion, don’t take it seriously. But this is what I think about you, honestly.
