I was strictly bottom for years. It was a combination of several factors. I have a relatively smaller cock, smaller than the horsehung fuckers you always saw pictures of, so it probably was a matter of confidence. I always got off on the pain of a big ol' hateful cock tearing my insides up (still do). Pull that big hateful cock out and if I saw blood, I wanted to taste my bloody ass juices. And I liked the feeling of my fuck shoot being sore for days......a nice reminder of what happened. As I got older, the more bottoms only guys that I met and I started topping. I loved the powerful feeling of putting my poz load in a fucker's ass. What a mind trip it was. And hey, if he wanted a bigger cock in there I would stick a dildo or a fist in there and fuck him on top of that. As a bottom, there are a plethora of more intense physical sensations going on. And aren't we in general all about intensity?
