A provider is engaged? I know many men are married and I also know many wives love to see their husbands with other women.... however how does a client feel knowing a provider is engaged?  
Providers would you ever share your martial status with a client?  

I dont do the "fake fantasy" bs...

and a few will get off on it.  

People want to feel special... important, your favorite, your priority, your focus.  Don't talk about a bf, or fiancé or other clients.  Give him the fantasy he came for.

I wouldn't be interested. Then again, if I'm in a relationship I'm not straying either.  

Some men remove their wedding band so their hostess won't feel guilty and withdraw if she sees it.
Some men remove their wedding band so their hostess will not worry emotional involvement and going full throttle into the "relationship"  

Why should I care if the provider is dating, engaged, or single?  I am there for a specific purpose and a set amount of time.  Sure while I am there I want all the attention on me but we are talking about a GFE not an actual GF.

If said john is getting too familiar I make up an SO. Otherwise it is none of his business.

and I sometimes enjoy the humorous stories about personal dating life, or weird shit that other clients do.  My ATF and I swap crazy stories all the time.  It's just part of the experience for me.

I like the idea. I'm always asked if I'm married or engaged. Just wanted to know what the majority thinks. Some guys are aroused if you've been with many men or if you are taken, so although I'm honest to a fault I usually try to tell them what they want to hear.

If she feels inclined to tell me, this lets me know two things, first off she's comfortable around me to tell me something that personal, secondly she's very proud of her relationship, and that's awesome.
