NO!!!!!

WTF, are you nuts?  If you have to ask that, go find another hobby!!!!!!

Swim

You can ask. I would say the odds of a girl whipping out test results for you to see are about 1 in 1 million. I'm not going to show you a piece of paper that has my full legal name, address, and other personal information on it.

You are also free to ask her if she tests, or if she is clean. She will say yes to both questions. Guaranteed. Some will be telling the truth when they say yes, some will be lying. Flip a coin to decide if she was telling the truth or lying about it.

You can also "test" her by offering extra $$$ for BBFS. If she jumps at the offer walk out the door. If she refuses, chances are you will be on your way out the door, but at least you will know she doesn't do that sort of thing.

If you want to take every possible precaution do the following:

1. Don't "camel slide" as it is called (private to private rubbing) without a condom. The risk of STD from this is slight, but both herpes and genital warts can be transferred.

2. Tell her you feel more comfortable with a CBJ. Most providers won't be offended by this request. The risk of transferring an STD via BBBJ is slight, but it is not impossible.

3. Either refrain from DATY altogether (she won't be offended), or use a barrier. You can buy dental dams at most drug stores, or simply use saran wrap. I can tell you from experience, that it is nearly impossible to orgasm when a barrier is used, but it is still very pleasurable.

4. (This one is the no-brainer) Use a condom properly for FS.

Only if you want to remain a hobby virgin...

for safety reasons, her name and info is on there.

Plus even with a test that's recent, there are risks always. Don't fool yourself, this is a risky hobby. Now don't go crazy it's as safe as it can be if you play safe.
But if you are looking for a fool proof 100% certainty you are not going to find it here...or anywhere unless you do not have sex, then you are safe.
If this issue is holding you back you may need to rethink this Hobby, it's NOT for everyone.

I will add this, though:  

It is completely possible for test results to be inaccurate because of the testing "window period."

Plus, they can be faked, etc.

Most providers don't walk around, carrying that with them all of the time, either.

Play safe, and you will PROBABLY be okay.  PROBABLY!

I was just with a provider that used hand sanitizer every time she touched anything that may have had my body fluids on them. There are providers out there who you will be able to not kiss, wear latex gloves while touching and do everything double covered if you want. You just need to seek them out. Use TER search and start with providers that offer only covered blow jobs, search further to find ones that do other restrictions like no kissing and no touching of the vaginal areas. make the choices that make you feel safe. I have hobbied for years, have done every act from french to greek with providers and am perfectly healthy. I credit my position to paying attention to warning signs and passing up on providers that flag them.

Keep it wrapped and you won't have a problem. And just as she will inspect your equipment, you should do the same with her. For instance, no BBBJ if she has mouth/lip sores, and I'd head for the hills if there was any sign of disease on her, ah, "female parts."

I'm tested every 30 days and I carry the test with me but I will not do anything bareback.You could'nt pay me enough.Read reviews and go with gals who have saftey in mind.
