hey dude, looking fit :P
i had that problem when i got started... it just took some time, and a lot of play, lube and poppers! With guys though it was about finding someone i clicked with that i really wanted to take it. I'm sure you've heard, tking a fist is as much about the connection with the other dude as it is about the technical aspect! Also, is he an experienced fister!?
I have been trying to take a fist for what seems forever, at least three years without success. My latest toy is a plastic traffic cone. It's kind of hard to get it to stay in place but my unique bath tub makes it pretty easy. I'm up to three sets of 100 bounces on it at one time. My ass seems to be openned up pretty much since a toy from Ft. Truff goes in pretty easily after I'm finished. My other problem is finding experienced tops with small hands. They are few and far between. Lastly, the only club I can find where fisting takes place is Slammer in Los Angeles and fisters seemed to have abandoned it. Very few times have I found anyone into FF and they now usually are only bottoms.
