I can understand your concern.  Yes there is an inherent risk of catching an STD anytime you have sex outside of a monogamous (mutually tested and negative) situation.  Asking a provider when she was last tested will offend in most cases but more important, its a mute point even if she answered.  She could have been tested that morning and may have a false negative.  Incubation period exists for most of the list. Lots of info on the CDC (center for disease control) website, its as accurate as it gets vs opinions.  Given that her answer even if honest won't give any guarantee I would skip the question but that's my opinion, you do what you are comfortable with.  This industry is not for everyone if you do your homework and find the risk outweighs the reward well you may want a different hobby. I can tell you I myself (I am under alias so zero reason to lie) have never had an STD. I have been agency and indy, I am tested every 3months faithfully and most importantly have NEVER been unsafe, meaning bb. On the flip side I have had men visit that had something suspicious looking and I had to refuse the visit ( 2 times in 3yrs).  There it is, the brutal truth.  I don't know if I have helped or hindered your position but thought a providers prospective may be useful either way.

If your having second thoughts. Don't do it brother! Most ladies regard their heath more than yours.  
By all means, Seek highly reviewed ladies and good luck.

frequently and practice safe sex.  If you see a well-reviewed lady, your chances of catching something are slim.

As others have said, if you aren't into this game mentally, better to pass for now.

...If you have researched the provider here on TER. She has lots of reviews. Several of her reviewers have written lots of reviews. Her reviews are good ones. You use a condom for intercourse (you could use one for blow job if you want) then you have done all you can do to minimize the risk. You can't remove the risk completely.

You do all you can to reduce the risk then go for it or don't. That's the best you can do.

Asking her will most likely result in a hang up (phone) or her asking you to leave or a crappy session because your question pissed her off, insulted her, or upset her.

If you ask what's she going to say? She's going to say everything's fine. What would you expect her to say?

Thanks everyone

Appreciate the info and realize (now) asking would be obnoxious.  Just didn't know what others had done, etc.
