It would all depend on whether or not I've slept with men who have HUGE penises. Sleep with one guy with a HUGE penis and I imagine it could stretch your pussy a lot so I think it all depends on the situation. Sleeping with one guy with a HUGE penis and then being able to fit two smaller penises in there would be understandable. I don't think it really has anything to do with how many guys you slept with but with the size of the penises that you've been with. BTW, the only women that I consider sluts are women who feel the need to sleep with as many men as possible, married or not, with no discretion at all. Sleeping with a lot of men doesn't make you a slut, IMO.
