I get asked that quite often, and sometimes they don't even wait for me to answer, and they say "I guess it's hard to have a bf and doing this" (which I agree, but it's none of their business, I don't ask about their wives unless they make it obvious they want to talk it). I wouldn't disclose having a partner even if I did anyway...

Similar to when they ask 'are you single?' or 'are you married?' These are personal questions which they have no business asking. I just tell them it's personal in a stern/flirty way so they have a chance to get the hint. If they ask again I turn the question back on them whilst stopping whatever nice thing I'm doing.

I always give a flippant answer, something like "nah I'm far too sensible to be married" and they usually shut up 

That question is the equivalent to "why are you sleeping around when you have a wife?'.

Nosy old gits who ask personal questions (and yes it does tend to be the older men in my experience anyway) are one offs for me and I do not see them again if they ask for another booking.

One man asked me if I was married or divorced and I just looked back at him and smiled but ignored the question. He seemed to get the hint that he should not have asked.  Another asked outright "do you have a husband?" to which I replied "maybe I do and maybe I don't"  and another asked how long I have been married and my "almost a month" left him literally open mouthed. It wasn't true of course but I enjoyed playing the game.

On the flip side though I have long term clients who I have known for over a decade and they have never asked a single personal question about my private life. Perfect!  They may just be totally uninterested or have a total respect for the rights and wrongs of booking ladies. Either way it is good.

I got asked recently 'Do you fancy me' to a client it did feel very awkward.  He was disappointed I didn't do dinner meets.

He also asked how long was I going to be doing the job for!  Honestly.

I never take my wedding ring off, so if anyone asks, I just wave my finger at them...... Sometimes this warrants a follow up question of 'Does he know you do this' - Proceeding by me rolling my eyes into the back of my head & very bluntly telling them he is downstairs watching TV if they would like to ask him themselves, that usually ends that little awkward interaction
