Wearing tight underwear is a bad idear - It crimps and over heats the nads - overheated nads are a bad thing.

Then there are other issues such as pressure points in the lower back and the groin which shouldn't be constricted. Blood flow in the legs should also be considered.

I only take off my pants for the right guy.

Oh, they're not unbearably tight, so don't worry. I'm not uncomfortable.
