Even for hooking up, I look for educated professional guys. I usually chat a bit on whatever app before agreeing to meet and if you're a "wyd wya" type it's probably not a match. Even a one night stand is better with some connection. Though recently (see my recent comments) I've had more random hookups that have worked out, too.
Physically, I generally go for my otter boys. Messy hair, maybe scruffy, no long beards. I need a handsome face and a good body to really get my engine revving. I've reached a point where if your face is not good, I'm not gonna fuck you, and probably won't even stay hard with you, anyway. That just means I have to like your face, you don't have to be a model. I like intense eyes.
Smooth muscle guys are good, too.
