My boyfriend and I have been together 4 years. The first two years we had a amazing sex life... Now we barely have sex. I tell him I want to all the time but he laughs it off. He says we don't need to have sex as much anymore to love each other as much as we do. We have sex maybe once every few months. Am I over thinking it? I caught him emailing another girl sexually but they never hooked up. He said it was for his ego. Do I just believe him that he doesn't need to be as sexual anymore? I'm lost and I just don't know if this normal in relationships.
