I just registered on there, and come to find out there are only, like, 12 trans girls on there for the entire state of Texas, and I'm the only girl listed for Austin.
Just wondering if it's something you all use for finding/vetting a provider.

There are a few of those "vetting" sites, all ask for personal information. Discretion and anonymity are cornerstones of this business. Divulging personal information to a third party website (and having to pay to do so!) seems contrary to both of those principles.

The only sure shot is at a social medium, Club,Lounge,Bar,GM rallies. Let them know what their getting into.lol Seems to work in most cities I've been. Very easy.No guessing or hoping involved.

Some girls swear by it, but I have never had occasion to, and never found it necessary.

It is not necessarily a bad thing that for you that other trans providers in your area aren't on P411.  

Hi been lurking here for awhile, never really replied to post or other things on boards. I have wondered that same question too (thanks for asking) as I ponder on your question a more important one comes to mind in regards to gentlemen who are ISO Trans-Providers which many (not all but some) see genetic ladies too, obviously they wouldn't review a real female and a tgirl from the same account which means do some have multiple accounts on sites such as P411 and other places??

If they have any guys at all they would use the same account.

I use P411. It saves time on both sides because it reduces the likelihood of flakes, no shows and games.

Is probably the best site out there IMO.

Yeah...but let's face it. A LOT of guys who are in to trans girls/guys don't want anyone to know because they're afraid of being ridiculed by their peers.  
Sure, a lot of guys aren't worried about it, but more often than not, that is the case.
It's an uphill battle, of sorts.

...I guess Ill just see how it goes.  
I agree, Jessica, being one of few is probably better than one of many, in this case

True. But, honestly, isn't that part of the problem? Guys who will fuck you but not be seen with you in public. I call that cowardice.

Yeah.
I mean, it sucks (no doubt) to be ok to fuck in secret, but somehow I'm not good enough for them to actually be seen with me.
Trust me...that shit hurts. Like...I didn't CHOOSE to be like this, contrary to what some people believe.  
No one wants me to be "normal' more than I do.  
But...I'm not, and that's just the way life is.  
I can either let that shit eat away at me, and allow it to keep me from being happy....or I can choose to accept what I've been dealt, and make the best of it.
People can fight over what bathroom I can use, or who I can marry, or even whether I should be allowed to live, but they can't take ME from me.  

I reside in Dallas I still use p411 but i preferred it better when there was the ad board up and not the available now.. I got way more business back then..  I know I am late to this posting..
