Raw Porn is a relatively new forum to the world of adult entertainment, but don't let that suggest to you that there aren't decent threads here worth taking a look at. In fact, Raw Porn has had a huge surge in recent months and you, the user, reap the benefits!
The gay section here has a pretty dececnt number of posts, somewhere around the 1.5 million region is a good estimate. The forums are broken down into 5 sub-sections: general videos, full movies, mega threads, Asian videos and fetish clips. The mega threads are pretty all-inclusive anyway, so if you have a particular type of gay porn you're looking for, be sure to check there.
Note that the Raw Porn forum isn't only for gay users, so be sure to specify when using the search feature that you only want the posts in the gay porn sub forum to be searched through.
