Not all women are built for hugeness
My wife is extremely tight. I have been thinking about getting the phalloplasty surgery done and decided that before going through with it that I should get a dildo of the same size and length that I want to achieve with the surgery (and jelqing/stretching) and try it with my wife. So, I bought a doc johnson’s 8” long X 6” girth UR3 strap-on cock with the harness. I couldn’t even get it more than an inch or two inside of my wife. She didn’t like it all. It hurt. And I had it completely greased up with lube. She said that if my penis was that size that she wouldn’t have sex with me. That, at least for her, a huge penis is not preferred.
My penis is fairly small (6” long x 4” girth) and she still feels very tight to me. My confidence is very low about the size of my unit, but at least now I know that any really huge gains are not in the best interest of my lady.
