Average 35 year old. I just wants one thing in life. Another cock to rub my own cock (underside to underside lengthwise). I want to rub cock to cock so hard that our underside skins peel off after hours of frantic rubbing and the insides of our cocks come in contact. I love to keep track of the time duration of the rubbing, the friction between skins and to look at the textures of the 2 rubbing skin, the microscopic ridges and valleys on the 2 undersides and measure their interlocking. I like when there is a large amount of skin to skin transfer happening at molecular level (fluid exchange, oil exchange, molecular exchange and even blood exchange).
