I hope that's not directed at me
If so, and we're all judgmental now. Why is it stupid? It's a sex practice. If I did it and ending up not liking it? Might be a waste of time but stupid? arguable. If I don't bother with something that might be enjoyable? Sure, that might be stupid.
You wouldn't be interested in that type of play? Do you know about it? I can make the claim that any sexual activity that isn't reproductive is stupid, but I don't because that's not what I believe. Potentially, it's an intense feeling. A hetero couple that I'm friends with
both do it, and tried to assure me when I was curious about it. It's just experimentation. The only stupid thing about me is my sad and pathetic nature that anything I've ever done sexually was scientific in nature, not for stimulation. If you wanna say it's why I do things, that's fine, I guess, but I research and care about the things I do. If I didn't, I wouldn't be doing it,
that would be dumb.
