I'm starting to have casual encounters from Craigslist (bi guy) with other guys. I'm into 69'ing mostly. When you are doing it with a stranger, is there any etiquette to follow, such as letting the person know you are going to cum? Usually that seems to be the case, but with the latest guy, he came without warning. I was on the bottom of the 69 so there wasn't much i could do. I typically go deep when I know the guy will start cumming, mainly to help swallow it all and not taste too much.This time, i didn't have that option and it was quite an experience. I swear the guy probably had a weeks worth saved up too.
