So I've been dating my boyfriend for over a year and a half, up until now we have never had the problem of him not cumming. Recently I will have to really try to get him off to the point where it's not enjoyable for me anymore. Taking nearly hours for me to do everything in my power to get him aroused and to his breaking point. He confessed he was masterbating quite often, should I be worried that our sex life is going down hill? Or is this normal at this point in a relationship? Anything new or crazy I could try and mix things up?
