It seems half the ads I see on many sites these days are TS.  I didn't realize that this was such a significant portion of the hobbying market.  Common sense would suggest that it is only a small fraction of the market, yet the high number of ads indicates the demand is there.  So what gives?

I also have wondered just why there are so many TS ads.

someone is lying

Don't get me wrong, there most certainly is a demand, but on some sites it really does appear that fully half the ads are for TS providers and I don't know ANYONE who honestly believes that half the whoremongers out there are interested in dick.

There are MANY men on this site who may have reviewed cis providers, but will never review a TS provider or tell anyone that they've seen a TS provider. I know because I used to be a booker for a TS provider and the amount of guys who booked with their handles full of reviews on cis providers was staggering. I often asked if it was their first TS provider and the answer was almost always no.  

and likely a great share of them life-long exclusive heterosexuals. We can quibble over how big or small the "small fraction" is, but don't pretend you don't know what the OP is talking about.

It depends if ads are "free" or "paid."  A paid ad has to justify its existence with cash flow.  Free ads only show supply, not demand.

Is the best way I can think to put it.  I watched a Youtube video where Lexington Steele and Nikki Benz were discussing a similar topic.  She was saying that in her opinion 75% of male performers were Bi-sexual.  I don't know if the number is that high, but then again I don't know if the number is that low either.  And what was once taboo (straight male performers banging men or TS performers) is now the norm and accepted.  I say that to say this, porn stars, nymphos, clients, providers are all the same in this sense.  We think outside the box when it comes to "normal" sexual parameters.  Societal views say it's not normal to have sex with complete strangers, let alone pay or be payed for it.  Some clients have an itch to scratch.  

...discussion board is the fourth oldest of TER's twenty general discussion boards.  It was created only after the General Board, The In Search Of board and the Suggestion and Policy board.  TER thought the subject of transsexuals should have a discussion board before Porn Stars, Newbies, etc.

If a provider is making very good money it means she has lots of clients, then why would she want to or need to advertise herself for new clients? Expose herself to LE or crazy clients? No way, not worth it.  When you're making great money you don't need the hassle of advertising or the need to hustle for new clients, because you're so good clients keep coming back. No need for advertising.
Even the hard core hobbyists on TER will tell you that some of the best Providers are UTR. Just check older posts.
Some of the really high demand (not necessarily expensive, some very reasonably priced) girls never advertise, yet they are always busy. They don't need advertising.

...was not based on economics, then it was based on fulfilling a need of perceived interest in the hobbying community.  It was a forward-looking decision by TER so many years ago considering that still today many TER idiots still disparage transsexuals:

I knew it!  I suspected all a long that some of these guys are on the down low.  I don't care, but I am worried about HIV which is very high in the gay population. I've met a lot of TS especially while living in NYC.  TS were once men or still operationally are who sleep with other men.  A lot don't use condoms, because there is no fear of pregnancy.  There is also a high risk of drug use in that population..  Be careful out there.

A lot of men are in the closet.  Straight men experiencing real penis instead of Strap on.  

First of all, TS providers are a relatively small percentage of the provider population, but they have to advertise more if they're going to pique the curiosity of the average straight male.  It takes years of noticing TS ads before a "normal" man will start to get curious.  Also, the percentage of scams is much higher in the TS market, so many of the TS ads we're bombarded with are fake.
