Can a man show signs of semen in his underwear without having sex?

Answer

Do women discharge and spot sometimes? Yes, and so do men. I'm not as mentally talented as some here who can think themselves into an orgasm, but I know very well that just getting turned on extremely will cause pre-ejaculate to discharge.

Answer

Yeah, it's called pre-ejaculate (pre-cum). When he gets turned on and that clear fluid seeps out of the top of his penis, that can leave marks in his underwear. I've been so turned on in the past that it actually soaked through my underwear and my pants.

Answer

The answer would be Yes! And I don't plan on going into details.

Answer

Yes! He can masturbate and have residue left over from the experience. He can also have semen in his underwear from dancing at a night club or from a lap dance at a strip club. He can also think/imagine his self into an orgasm.

A man can have pre-ejaculate with a erection without having a orgasm. it goes to the tip of the penis and used for lubrication of the woman. a bilogical thing. men can have a erection just by waking up in the morning. some healthy men have alot of pre-ejaculate before they ever engage in sex.

Answer

The answer is yes, of course! Ever heard of "wet dreams"?

Answer

Yes and without "wet dreams" or anything associated. Semen can easily leave the man without stimulation or realisation. It can just 'happen' like most biological things in life. If someone uses this thing as a reason then they are insecure and uninformed. Accept that things can happen.

Answer

What's more, it's perfectly possible for a man to have sex and leave no telltale signs at all on his underwear. So using underwear to decide whether or not a man is cheating is likely to be very misleading.
