Well then, maybe you should tell them your own history as well. I bet you wouldn't feel comfortable to tell them specific things about yourself either and at the end of the day if you like what you see then go for it, if not, then don't. Who cares about the past. We all have past. You wouldn't like if you were denied service based on your past. World is progressing and if you cannot follow, it's your problem. If it walks like a duck and quacks like a duck and looks like a duck it's a duck. Same here, if there is vagina between their legs, they are female according to the law and calling them anything different is not only disrespectful but also offensive. There are a lot of girls in this forum who have been outed without any evidence and even if there is an evidence you breach their right to privacy. Not to mention you bring harm to their business and personal life.
And the answer on all your doubts is simple guys. If you don't like what you see or have bad feeling about particular girl, then just don't do it and go for someone else.
Hi "Sean", have I touched a nerve? Your one and only post in nearly a year. Maybe you would prefer to be addressed as "Shawna"?
A man masquerading as a woman is not past history. It's current. It's what they are doing right now. A vagina or a cock is not the indicator of male or female, it's the presence or lack of a Y chromosome. No matter what the Gender Recognition Act 2004 and the Equality Act 2010 may have lead you to believe, (there have been plenty legal cases which show it's not quite so cut and dried). Plus, I'd bet very few of these SP's have acquired a lawful Gender Recognition Certificate in any case.
Regarding revealing my own history to a WG. I often do talk about my life with WG's. Although, those conversations doesn't usually happen in advance. If a WG wishes to ask me questions she can go ahead, but I may choose not to answer them or decide against booking them. The difference is, I'm not the one putting out a profile to advertise my services to them, and charging them for that service.
And to respond to your final statement. When I have my suspicions about an SP I do visit someone else instead. This thread has been very good at confirming when my suspicions are spot on.
