Some of the ladies here are very low volume, and some are higher volume. By the same reasoning, the strippers in that bar, or any other bar, may work six nights a week, or they may only work weekends. You have to decide how safe you want to stay, and take all the necessary precautions to stay that way. If you are with a lady who doesn't seem to be taking all the precautions you'd like to see, excuse yourself and leave. Remember that it takes two to tango, and you are just as responsible for safety as any lady that you see.

You are basing your assumptions on what you hope to be the case, not reality. Was the stripper offering unprotected sex? There really is no way to know how many came before you or how many came after.  

Don't take any risk that you don't feel comfortable taking but don't kid yourself into thinking that one "type" of lady may be safer than another.

you have no idea who they offered the same thing an hour ago, or yesterday, or .....

Unprotected sex is never a good idea.  If you decide to have it with a stripper, exercise the same precautions you would with any other girl.

Being paranoid is infinitely better than being dead.

It's crazy to think that a stripper entertains any more or less clients than a provider. Some will, some won't. It's impossible to know, for any given stripper or any given provider.

And "as long as you're using a condom" you should be OK from the "big" diseases (HIV, clap, syph), but you can still be exposed to crabs, genital warts, etc. Basically, all the stuff that doesn't involve bodily fluids, but are still classified as STDs.

Pick a girl with a shaved coochie - no crabs, and you MIGHT be able to see if she has warts. Not likely though...
