Do you immediately lose interest in someone you just slept with?

Depends on the reason for sleeping with them.

If it's a friend with benefits thing then my interest in them is purely about sex. If it's good, I'm still interested in sex with them later.

If it's a one time hookup type situation then, yes my interest is immediately gone right after sex. Leave my bed immediately lol.

If it's a relationship then no, in fact the cuddling after usually will gain more interest than the sex with me.

I think this poll needs more than "yes/no", since it's more like how much interest is lost and it's not the same for all people you sleep with.
But it is a good question. I asked one like that: https://similarworlds.com/relationships/5490716-Could-the-only-reason-you-fell-in-love-with-your-friend-be

Not that I’ve found. They all left a permanent mark with me.

Nah, it usually just makes me more interested in them. 🤔

Granted, I haven't slept with that many people to be able to tell. Guess I gotta up my game. 😤

If the performance was bad, yeah. But that only means sexual interest. I may still like them as a person.

My wife said that happened a few times when she was in college.

Sometimes, but mostly because of work

Usually it's the opposite for me. Sex is a bonding activity, whether I want it to be or not

That depends on the reason you slept with them in the first place. Or, how good it was !😉

Nope. Usually if I sleep with someone, I'm interested in them long term.

No, that would be a reason to increase interest -- unless there was something disturbing about the experience.

Depends how good they were.

Depends on how cute her butt is.
