here's a basic rule of thumb though; the more you are sticking someone in (and the larger objects you stick in the looser it gets). It's quite easy to tell if a girl is pleasuring herself on a regular basis because her hole is usually looser than normal.
I don't really care what anyone says or thinks, but it's true as xDeathlySilence said that sometimes 2 fingers should hurt the girl. i dont want to get into anything over personal here or anything, but i know for a fact that somegirls only can barely have one finger up.
It's all a matter of how regularity and maybe it might be a lot different if you've had a kid or kids (i don't know cause i've never dont someone who had kids).
But in general yeah, some women are probably lying when they say they can't fit more than 2 up there. I dont want to make it outl like im calling anyone a bitch or anything. The truth is, darwin is kinda right; many girls always claim less than capable. But from experience I know some can be quite tighter as to where a single pinky would give pain... anywho.
u know the best thing about meaning a man?
men probably jerk off a lot more (on average) than most women (on average), but fortunately for men their genitals don't fluctuate in size or shape when you play with 'em! lol so chicks can never really tell if a guy has been fucking around or masturbating a lot, but on the contrary it's usually pretty easy to tell for guys.
