UpLust.com is an alternative service to sites like Pintrest that offer access to adult entertainment content. What you'll find is a site that has a number of hashtags split across the platform that allows you to really focus in on exactly what it is you want. Now, for your convenience, I've linked you directly to the gay segment of the site: you're free to go deeper than that if you have a specific taste, though.
Up Lust's major features include its social media arrangement that basically give users the ability to share their material. I don't quite know how to explain how it functions differently from a pin site, but I think explaining it as a cross between Tumblr and Pintrest is a pretty accurate reflection of what you're getting here.
Content can be sorted based on upload date, number of views and my personal favorite, rating. Updates come in multiple times per day and of course, if you want to put your own material on there, you are free to do exactly that.
