Need advice on this? the only way i seem to be able to hold down a complete stiffy is to bress down at the base of my cock along the top. I get very hard when a girl touches me with her hands, but during sex etc i'm only on a medium one after initial penetration with a full hard on. I dont really want to wear a cock ring or take viagra are there any suggestions on here as to how to maintain a full hard on so i get maximum pleasure as well as my receipient!!
