I've never had a straight up booty call with a girl - the closest thing was a 1st date where she came around and we talked for a few hours then ended up having sex, but it definitely didn't feel transactional like a booty call.

But let's say we established that we both just want to have sex and weren't really interested in anything else

When they come round, do you bother making small talk? Do you bother pouring them a drink? Do you bother putting on a movie?

Or is it basically walk in and - assuming you're both actually attracted to each other - you start hooking up right away?
