My penis is curved and not long(about 5,7-5,8 inch)and sometimes during relations it slips out of the vagina expecially when she is on top..This happens because my penis is a little short or curved? I have heard that women like it cause it feeld better,... BUT! If we are talking about length a curved cock does not go as deep as a non curved cock...That is my problem there... my cock is .5,8.if i use a tape to measure it..... but if i use a ruller it is 5.4" cause of the curve..... SO the question is, is a 5.8 inch straight cock better then a 5,8 inch cock with a curve that goes 5.4" deep...? A long penis,obviously,doesn't slip out easily..But i think that the form of the penis can be important.. Which is your opinion?
