Obviously there's a market for this. But if it's not your thing. Let's assume no mention of it in the ad, and when you show up you have a strong suspicion she's full  on post op? So no more dick but your gut says she used to have one. Do you ask? Do you bounce out? Do you go for it?

First of all, what's the odds they will tell the truth?

You're probably right. And in all likelihood I'd bounce. Of course the counter argument to leaving is that if anyone knows how to please a man it'd someone who used to be a man......lmao

As long as she's post op it's fine by me. Original or after market pussy is still pussy to me. I know that I'm in the vast minority on this one. So be it.

If you only suspect, they must have done a pretty good job.  If you know,  well, then they didn't do such a good job.  In that  case I'd run, run like hell.

ask her when was her last period..  See how that conversation goes..  

since the same argument could be made by a gay man who looks like a man, the fact that she looks somewhat feminine would not be persuasive enough for me to take the plunge.  If I wasn't sure, I would err on the side of passing on the session.  As Fisher says, I'd give her something for her time, and politely tell her it's not a good match for me.    

I got taken by a TS many years ago in Bangkok! She was attractive and shapely! She was also a good kisser and gave a mean blowjob. It was a late night hookup, and she only offered oral! I figured it out after the fact, so call me dumb! I was a few years out of college at that point, and back then it probably cost a couple of bucks. It was probably the cheapest BJ I ever received. The TS part was a hunch back then, but in hindsight it was obvious. No harm, no foul!

Did you 69?

A provider’s medical history is truly none of your business. If you don’t want to go through with a session for whatever reason, pay the provider for her time and leave quietly.

Definitely not a fantasy or I'd just go try it. But if never come across the scenario and have no idea how I'd react other than that I wouldn't be a scumbag about it because that's not my style. I'm a polite person. And I don't agree that medical history is no one's business. I may not expect a provider to share their medical status but as part of the trust I'd hope people would be honest about at least STDs or other illnesses, even if that simply means canceling an appointment without explanation. I'm sure I've been with some ladies who didn't disclose but if I caught something I'd probably stop until it was resolved...but again as I said I'm not a scumbag, so to each their own.

a) A provider's health history is none of your business.  
b) If something makes your uncomfortable, walk .. a gent pays a cancellation fee.
