There is no set number sleep with as many as you like as long as you are safe.
Ya know the only reason that word exists in the first place is a guy said it to scare a girl into thinking sex was bad for you, but it was okay for them to sleep with as many people as the wanted ,no one calls them a whore.
What a double standard just remember how many people you sleep with is your business and only yours ,no one else needs to know.
