This works both ways. The 300lb gorilla might have a horse cock that makes a woman's eyes pop out, and it is not carte blanche to fuck like an animal - unfortunately, this is more true than not. Or, something reasonable, combined with empathy and skill, is an explosive combination. It is a familiar line - what you do with it that matters. My preference is really only something above average, I love girth. I really love riding, so I want it all inside... all of it. When the craving comes for a cock inside me, I have to feel all of it, it needs to touch everything. So figure out how long and thick that is. Oh, and banging my cervix... fuck no, that hurts.
