I can testify that the some of the ABSs in the Dallas area are excellent, though I have struck out a few of them repeatedly and therefore haven't returned. Unfortunately, I have yet to have my ass fucked, but I have been on my knees with a cock in my face and one in each hand on two different occasions, eventually draining all 3 each time. I have also managed to drain 7 in one visit, though most of the time, it is only one, maybe 2.
I can usually find the first cock in relatively decent time frame, most likely because I look more like a guy that would stomp your ass if you even mentioned something homosexual, much less drop to my knees and take you in either hole like a total bottom slut. I think it's a turn on for some guys to deposit their seed in an extremely masculine looking guy, it gives me a slight advantage when 90% of the bottoms are smooth feminine looking twinks that weight about 110lbs, and the rest are short overweight and balding.
