I'd like to invite you to my community AdonisMale.com. We're not a direct Tumblr social media alternative, but we do offer a modern community experience of forums, blogs, albums, and social clubs.
We've been online since 2013
We're free for all users + paid perks (similar to the donation system here at GTRU)
We're clean and ad-free
We're home to some of the world's most beautiful and largest gay galleries in Playgirl Magazine, Vintage, and Male Models
If you'd like to check it out, be sure to say hello to me in the Introductions board!
