It's neither straight nor gay. It's just guy. It almost goes without saying, but all guys like to play with their dicks. A man's dick is his favorite toy. And all guys, gay and straight, like to watch other guys play with their dicks. Guys especially like to watch other men reach a climax and ejaculate.
It's really unfortunate that participating in a circle jerk is so often looked upon as an adolescent activity, when in reality men of all ages can have a good time jacking off with their buddies.
I've never done it an dit does not especially interest me, but I do know people who did this when they were youngsters and it seems to be quite common for young men to do together so I would say it's more or less 'normal' for straight men to sometimes indulge as a casual thing........
........Probably the latently 'gay' guys in the group find it more interesting than the straight ones, but I could be wrong....
