I know a lot of hobbyists are interested in prostate/anal play performed on them. I think it would be a terrific addition to the provider search criteria (maybe below 'rimming,' lol). Also, it might be helpful to add something to the existing 'anal' category besides a simple yes and no. For example, some of us don't offer anal intercourse as a menu item, but still enjoy toys and an occasional finger. Right now there's no way for potential clients to know that unless it's written up in a review.  

interesting play on words in the "subject"  heading!  and excellent suggestions.

if i am offered something extra off the menu..i simply list it in " Other Services Offered " on the review form..i just list " prostate massage "..never had a problem getting it approved..

Problem is how far does FIA get. Maybe FOA (on) ?
