Do guys sweat a lot?

I sure do, but deodorant can't cover up everything. Truth be told, guys who are prone to sweating more are typically more healthy. Of course, if he shaved or trimmed his pits, they would smell less bad. Also, you get used to your own smell, so he probably doesn't realize he stinks... and to be honest it's really embarrassing when someone points it out.

I find that a problem sometimes when I think I have enough on (I'm smelling good leaving my apartment) and get to work sometimes I have to do the armpit test cause I'm like I don't know where that smell is coming from is it me? But then again it could be just the kind of deodorants he's using he may have to find a certain kind that covers the BO.

I smell by the end of the day not like I'm gonna die but just enough to be like damn I need a shower. I don't wear deodorant because it can cause cancer because deodorant clogs the pores so you don't sweat which causes bacteria to build up in the armpit area which leads to your breast causing breast cancer (in guys or women)

Guys can't always help the smell. It's kinda natural to sweat lots!

Some guys do. I think some people are unfortunate in that they have stronger smells and have to work at it a little bit harder. It might be that he is trying and thinks he's doing well, but isn't quite there. I would think he's unaware of the problem. But it is a major problem. I'm not sure how you bring up the subject with him...
