iv read that a woman can feel more from a half inch of girth than a inch of length and that an inch of girth is worth 2 inches of length. i was just wondering if there was some truth to that. if so then what would be the difference in the fullness feeling between average girths like 4.5, 5, 5.5, 6 inches and even bigger? i do realize that a guy cant just have girth and think he is fine he does have to have enough length to get in there lol so what would be the minimum....around like 5 inches would go with any girth and get the job done?
