Of the five clients I saw yesterday, I only fucked one.
I find that if you give great BJs they don't much bother about penetration - they can get that at home. What they don't get is oral.
I find the finest thing for a sore fanny is a salt bath. You have to let the normal 'flora' return after any kind of injury or infection, and that can take up to a week.
I rarely allow fingering; they haven't got a clue!
