I've seen uploaders tag bodybuilding videos under "Hunks", "Softcore", or "Wrestling & Sports". Personally, I think "Softcore" is more appropriate as there are (unfortunately) no graphic sex scenes in them. Additionally, keywords such as bodybuilding, muscle, flex etc. would greatly help the gaytorrent search.
The anonymous status is necessary in case of DMCA complaints. However, there are certain signatures that can identify an uploader, such as unique phrases or symbols in the titles or descriptions, that would be helpful if you wish to have people know it's from the same source i.e. you.
I look forward to seeing more of your torrents, as I was pleasantly surprised to see a lot of new bodybuilding behind-the-scenes and pumprooms videos this week. I'm guessing they're from you
