There on average a weird maturity level thing that happens to most people give or take around the age of 25. (To me it was 27, but I didn't start dating until I was 22. I also think I was repressed due to a rape. Yes, I am that open) I'm not saying this doesn't happen early, but it's rare. It's 25 being stepping stone. You are quarter of a century old, so mortality sinks in.
Yes, I know I am going to get the "you're wrong, I never grew up." Again i said this for most people. The thing I've seen it with are the older people on here, fetlife, and a little on collarspace. The ones in their 30s and up.
It's different for everyone. Some want to settle down with kinky spouse. Some want to figure out how to have the kink around their kids. Some are trying to figure out how to balance their fun with their work.
It just they had their craziness in and want some kind of responsibility and/or settling down. This why on my previous rant mentioned under 25. (Again this just an average number.)
Please do not tell me I'm wrong, because your suck on a number.
