My roommate sits down to pee?

Okay this is really none of my business but I'm curious. I've noticed that my roommate always leaves the toilet seat down. Even when he pees. This is obviously a little odd since he's a dude. He is really overweight so I was thinkong maybe he has to sit down because of that but idk..

I don't want to ask him because that would be awkward so I'm asking you guys. Do you know any guys that sitbdowm to pee and why? Sorry if this seems ignorant/rudebim just really curious.
