I'm new to the hobby and have only used it to meet TS girls.

You're the guy who pays and you control the sex.  The girls can't force you to have bareback sex!
I do not believe any guys who say otherwise.
You do what you want &  how you want it to happen.

I have had the exact opposite experience with the last cpl. of T.S. providers I've visited.
 They put on a condom before we start anything...(which is a major turn-off for me/ can't stand the taste
of latex)..I can understand them putting a cover on me for oral..in case I had something; and the fact that they're seeing multiples of guys per week. But they seem to be, (as far as I'm concerned) overly concerned about catching/spreading any kind of STD..They would certainly never do anal bareback..(nor would I allow them).  
 Who knows, maybe it's just the providers I've been meeting, but "bareback"(either way/ her or me) has never even come up. I just thought it was kind of a given.  
 I'm trying to come up with a polite way of asking if I can give her a BBBJ BEFORE I drop $$$'s so I don't end up dis-appointed again. All their ads say if you mention anything of a sexual nature on the phone they'll take it as grounds to hang-up

Is that you?

Ha ha.

Not sure what you mean about something else going on?

Totally agree - of course - just was surprised they were willing to do so ... thanks for the feedback.

Not sure I understand - opposite in what sense?

Because it seems that it would be extremely risky to do such a thing.  But it does happen.  It's made me take a serious step back from the hobby and really pick and choose who I see.
