Hi, I have problems with ejaculation during sex I cant cum. When I masturbating so no problem and I can always cum. The problem is not the girl, she is very attractive and I like everything about her. I am only on 150mg trt. I also have to say that I use sildenafil before sex, could this be causing the inability to cum? My dick is really hard but maybe the sildenafil is causing the numbed? I haven't a blood test, but I think it wants to measure e2 and prolactin. Would cabergoline help on the cum? I read that guys on cabergoline can cum very easily Thanks for the opinions
