Would it be reasonable of straight men to leave a gay porn scene after they cum? Well....I think so. If I were on a straight porn set, would I leave after I came? Hell, yeah! I wouldn't stay on the scene one second more than I have to because I inherently don't do pussy. Now maybe I would stay because I have a strong work ethic but if I could leave, I sure would take advantage of the opportunity to leave the scene immediately.
