My policy this year is 'naked' lol. Arrive and strip, shower and lie on my bed. Mostly uncovered all night and all morning. It's been very hot so its going quite well so far. Going to the bathroom, shaving and going to and from the shower ... all naked. I enjoy the non-sexual caual nudity of male dorms. Lots of big floppy cock!
I'm not looking for sex or into making anyone uncomfortable about sexualising the dorm - often I'm with the same guys for up to a week so the whole experience needs to be very comfortable and relaxed. A dorm is home for those in it and there is no place for making others uncomfortable.
That said, I woke up on day one of my new policy to a great blow job ... some guy couldn't resist once everyone else had gone for the day. Actually he did really well with swallowing a big load the night before ... prior to the other dorm guys arriving.
There's one guy in every dorm who wants your cock. The main thing is to stay very chilled and natural ... and let other guys explore what they are comfortable doing. Creating fun opportunities for exploration lol ... guys can't decide what they like until it's in front of them lol.
