Back in the day, when I was going through my cum-slut bottom phase, I wouldn't even consider being with another guy of "average" size...if I wasn't tantalized, nothing was going to happen! He'd HAVE to be substantial, or it wouldn't wake that wanting, inside of yours truly. It not only had to be big, but circumcised as well. Otherwise I would stay in my default, hetero mode and go home to my wife and bury my face in her most delightful, hairy vulva.
