I recently created a community for the practice of semen retention. It is an ancient practice and has ties to Taoism. For me and others it is largely for the sake of self improvement and spiritual / material progress.
I posted on a new communities forum and the post almost immediately has garnered several downvotes. I’m genuinely confused as to why. The practice is not hurting anyone, nor is it rude or offensive.
I expect you got down votes because whatever posts showed up on feeds for people that disagreed with the idea. The default home page is basically pulling posts from everywhere so it’s not just people looking for that niche that will see the post.
People often disagree with things that are fringe and when you post something online you open yourself up to criticism. Personally I would also disagree with the idea but I don’t think here is the place to get all debaty about it. I’m sure anyone can find the criticisms with a quick Google search along with debunking of claims about such practices.
