I'm a straight gal who watches gay porn frequently. I have noticed a trend, which might not be a trend at all, maybe its just the vids i happen to watch. I've noticed that a lot of bottoms are not very hard when they are getting fisted, fucked, etc. The tops can be stimulating them anally and wacking them off at the same time and they wont be hard. The bottom can be stroking himself and still struggle. I've also noticed in amateur vids that the bottom will have tight cockrings on and still not be real hard. Is there a reason for the bottoms not having hard erections for the most part? Is this why cockrings are so popular among gay males? I hope this make sense to someone as i'm curious as hell to know!
