^ It's simple. Respect their sexual boundaries. If they don't want to do anal I don't think anything will motivate them to do it. Maybe money (maybe) but at the end of the day it's their choice if they are comfortable with it or not. Find another performer who meets what you like sexually. Me personally I don't want to see any of my favorites do a sex act they are not comfortable with especially if they feel like they have to do it for their fans and not because they warmed up to said act and wanted to give it a try.
