Ahhh, so you have a big one too! That's exactly right.
My buddies and I used to always get in fights about whether a bj or sex was better. To me there wasn't even a discussion there. Bj's are just an appetizer for me, at best. I realized later on that it's the girth that ruins a bj for me. There's just no way to get any momentum going when she's trying to mouth da soupcan.
There have of course been a few rare exceptions, including my current gf. But I still prefer to let loose and just tear up that puss...
