@fissile well yes, but that phrasing would way too often lead to misunderstandings

like, when I’m asking someone "wanna sleep together", that’s literally what I mean. Sleeping. Not fucking. The latter might potentially also happen—just like chatting or cuddling—but that’s not what I’m asking about then (though tbh might be hoping for if that happened before, but I really should get in the habit of clarifying that more often then).

Also if I’m getting asked that, that euphemistic meaning would likely fly right past me and I’d be taken aback if there suddenly was some expectation of sex instead of it maybe naturally evolving, even reducing the probability of actually having sex (and it’d definitely be less good sex)

Otoh, simply asking "wanna have sex together" does work quite well, and can avoid the logistical efforts of a sleepover if that’s not really what you’re looking for
