Can someone tell me the psychology of why someone would just want to sleep with everyone ?

Just curious, why would someone just want to sleep with everyone.

What’s the biology, psychology?

I didn’t want to cater this question towards men. But this specific actions are more prominently towards men. I’m aware women do this too, but not as often.

Men and women please give me insightful, genuine answers. Just curious how the human mind works.

This community is for curiosity, not karma farming.

Thanks :)
