I've been dating this person for a month now, and we've been talking since July (we know each other from college). I've learned that they have had three sexual encounters with each of their x's (we've never had sex), and it makes me jealous/anxious when I think about it. I've also have had my own experiences, but whenever I think of him sexually, my mind moves to the other girls he has been with. It makes me feel small, not important other uncomfortable emotions. Sometimes the thoughts and feelings get intense, and I want to break up with him, so I don't have to deal with the complicated feelings anymore. Any advice?
