Servicing a female for extras? Or general massage?
Not sure how some will feel about that.
I know quite a few lesbian shop workers, but they all have girlfriends. Using a guy for money is different than seeing a lady for money....i think. I know several who have worked with couples, but mostly its the wife/gf getting excited at watching her partner in action.
If its a lady looking for action, money talks. Im sure there are willing providers. May be best to look at the private market.
