My partner is 59, quite fit. He does not smoke but drink a lot. Recently I noticed that sometimes during making love, his penis remained stiff even after he "came", and there was not much sperm/fluid came out. He said the reason for this was because I was not relaxed, so his penis was "chocked" because my virgina became too tight for him. But this didn't happen before though, I wonder if this is the reason?
He takes blood pressure medicines, could this be the reason? Could you help please?
