Thanx to both of you for your reply...
@Klythez...yea i did mean the cleft...i did understand wat you said..but even when women stand straight for some we can see a lot of the cleft..but in some i couldnt at all..so is the cleft size and correspondingly the size of the vaginal opeining different for different females??
@Tidaho...this is only one of lotta doubts i had...even at 16 we didnt know a woman's anatomy...we know there was an opening in the front...all we thought was...the penis was pulled and attached to the rear end of females...and we knew they squat and piss so we thought the would piss from behind...lol..lot of such illusions..not me alone...lot of us...there was no one we could ask...we couldnt ask girls...in our society parents arent close in such things..ive no siblings too...so we were in the dark for a long time...and still are...
