Hi Jay, OK some us men could do this for round 1, 2, and 3, it all depends just how sexy we fill at the time, but to say it smells, in not sexual etiquette, is he on any kind of antibiotics as this can make our male sperm smell, so it could be him, but most men love the smell of a women, so now a question I take that you are clean going into sexual encounters, again a question so if that is his excuse, how come he did not say anything in the first round, or as you said round one.
Please come back.
Good Luck
Have you never tought he could be cheating or jacking off ?
What do you mean you went one round? Were you doing it again? Usually for the male, the second time around is less erotic and maintaining an erection takes a bit more consentration.
well u didnt say how long u have sex in the first round and it seems from ur statement that ur boyfrnd has problem of erection and he needs some counselling he need to consult a sexologist
I would personally just talk to him about it, relationships are based on more than just sex and if you are just having sex to try to keep him around, that isn't cool. Relationships function on a ton of communication and honesty, if you think he has something to hide, just bring it up to him. Don't feel blamed, that is the worst thing you could do. Don't keep your thoughts bottled up inside, let him know what you are thinking, that could be for the best.
Good luck to you!
