Need some advise please! I have been with my boyfriend for 4 months and he cannot cum from sex. This includes oral, handjobs etc. When we first met he had a high sex drive but recently it has been really low. He has communicated that he finds being unable to cum upsetting and it’s bothering him but we can’t seem to get to the bottom of it. He can cum if we masterbate and watch porn together. He has lost his libido completely and we are unsure how to proceed. He also cut back masterbating. I am also his first sexual partner. Has anybody gone through the same?
