I found a higher resolution version of the same image. I did some reverse image searching and it looks like this photo originated in an Xhamster photo gallery. Unfortunately a while back all of Xhamsters photo galleries were removed or deleted? I frequent Xhamster a lot and everyone's photos were labeled as "under moderator review" and still aren't showing up. And any links to old galleries are either redirected to a completely new gallery or don't work at all.
This was the link that I found that supposedly has this image: https://xhamster.com/photos/gallery/nude-male-selfies-9497003
