I'd call myself a situational exhibitionist. Back in college, the 3 guys I rented a house with & I would have skinny-dipping parties & invite a whole lotta girls. (It always ended up all our friends from the drama & dance department who showed up.) Nudity was totally optional, actually, & we only lost the clothes a few times. I was never an instigator & only got nekkid when my buddies did. Otherwise, I'd keep my board shorts on. (There was never any sex at these parties - we were all too drunk, anyway.)
As for voyeruism . . . Nope, not for me. I've never liked watching porn, it just doesn't do it for me in any way - I needs me a real girl to get all excited. My first college roommate in the dorms, Ray, was always sneaking girls into our room (not like our RA cared, really). I walked in on him & a girl many times (I think the boy majored in pussy) & I always closed my eyes as tight as I could, tried not to listen, fumbled for what I needed, & got out ASAP. Ray would just keep goin' at it like I wasn't there. Ray had a very large cock which, I had to guess, had to be right around 10 inches. I know this because he slept nude & always got morning wood. I have 4 older brothers so I grew up seeing a whole lot of dick & it was no big deal. Seeing other guys just doesn't do anything for me, either - I just don't think of other guy's dicks in a sexual way. (But I can just think of pussy & I get all gushy . . . )
