Crazy idea.
That night if the party the player has to roll charisma to flirt and do the one night stand.

And the proverbial Constitution roll ...
( For those new at D&D : it is a classical for DMs to ask the character(s) to do a Constitution roll to determine how long they can last in sexual activity before falling asleep or other more shallow notions. It is dumb and more common for younger DMs. :P)
