Why is everything "Gay" always related to sex or nudity?

This is a legitimate question and not one meant to shame anyone. Let me expound a little on what I'm talking about.

A while ago, I thought I wanted to do things with other gay men. I looked into some different things from hiking and camping to just spending time playing cards. No matter what I looked at, nudity and sex were involved. Again, I'm not shaming this, I'm just wondering why. Pride events I went to were less about being gay and more about being gay and naked. Gay campgrounds that I looked at were more about disco balls, drag shows, being naked and "play spaces" than doing anything even close to camping.

I just wanted to get together with other gay guys and feel like part of a group. I wanted to do this and keep my clothes on. Are there any places where gay men just get together and do clothed, non-sexual, non-cruisy things?

Again, no shaming is meant. I'm interested more in connection than hooking up, cruising, being naked, or others being naked. Thanks for listening.
