Quote: I cant help but feeling that him not being able to ejaculate is a bad sign
I wouldn't read a lot into this. Sometimes we have no control over the body's responses. It's much more significant that he says he loves you and that he initiated.
I had a bf once who had a hard time coming unless he got a LOT of friction... so regular intercourse and oral sex didn't always produce an ejaculation... the smooth surfaces didn't produce rough enough friction. Yeah, that was probably from too much MB in his teens and later. I was in my 20's and too naive to read anything into it. It didn't bother me in the least... Alas, now that we're older, we sometimes imagine too much for our own good.
