Do any other gay guys not really "check out" men?

Very rarely.

There are times when I attempt to decide who within a room I find most attractive if I have nothing better to do, but even then it is largely based face, structure, demeanor, etc. It hardly ever turns sexual. I am most certainly not demisexual, however.

 

That's interesting. I do that as well with girls, but I don't really get a groin response nor does it really turn sexual unless I want it to (or when they start getting really close to me).

With guys though, I also decide who in my line of vision looks good. If they got a nice physique then that'll get my attention. I suppose I'll make comments in my head like "He's a good looking guy".

 

Exactly. It is essentially a mindset of "If I had to choose to be with one person in this room, who would it be?". Which is why I would consider it more people watching then checking someone out because it is more about being curious of my own interests and who I would choose than who I actually plan on pursuing. They might not even be the type of person I could see myself being with.

Now, if there were someone that I was extremely attracted to, then I might check them out and let my mind wonder. Otherwise, I am too much of a heavy thinker to pay that much attention to random people.

 

Likewise. I feel threatened by other males in general (whether or not I find them attractive). I feel nervous around attractive women and I do let my mind wonder in that sense - but in terms of same-sex thoughts, it's nothing more than "He's got a nice body" or "He's good looking" yet that still gets into my head and makes me think I'm something other than straight - even though I believe I'm pretty much heterosexual.
