I have an above average penis. Not so much in length — 4 cm longer then supposed “average” but in girth. In my adolescence the teen girls complained about pain but when I had my 1st sex worker ‘experience’ she was chafed with my body & performance. On her advise after relating the “pain” stories to her, she gave me a Chinese lube (forgotten the name!) & also mentioned that cow-girl position will enable women to take as much from me as they needed only!
When you get into long term relationships (I’ve had three) the ladies seem to customize themselves eventually to be able to enjoy sex with you to the hilt.
