This question is on the sexual part of me and my girlfriends relationship. She really turns me on, but when she starts to give me head, I begin to lose my erection. I’m not sure why this is but it is causing problems. Right now we are not having sex because of personal reasons and she wants to go down on me. The other day I lost my erection and she became so irritated that she left my house. I don’t know what to do because I can’t control it but it is killing her (and me). I have tried to maybe talk about doing it differently but she basically gets offended if I suggest anything because she says she hasn’t had problems in the past so she isn’t doing anything wrong. I love her and I don’t know how to fix this, what do I say to her?
