You have nothing to be worried about.
You are safer from HIV, and STDS with a working girl than you are with a random girl in a one night stand.

yes this is far away from the US or south america ... where often can find druggies/mentally ill persons working..

would be good night for the agency if you as a client get caught with a STD and it came out. all agencies do have a license in Holland and need to follow some regulations aswell, but there is a small chance with everything. however rather slim...

I will say, I’ve seen hundreds of ladies over the years, in the RLD in Amsterdam, from SS there as well, in Vegas, here at home, etc., and never caught so much as a cold. Not once. And BBBJ is standard over here.

If you’re seeing ladies from high-end agencies or reputable indy girls, your odds of getting sometime are very low. They take care of themselves, they care about their health, and they, unlike most women, have a financial incentive to stay healthy. As long as you’re not engaging in stupid, risky behavior (and the types of ladies you ideally want to be seeing shouldn’t let you engage in such behaviors anyway), you should be fine.

That said, I do take responsibility for my own health as well. I do always wear condoms (except for oral), I get tested regularly, and I got the HPV and hepatitis vaccines. Just be responsible, don’t take stupid risks, and you’ll be ok.

The worst thing that I have caught from a working girl is a cold and a yeast infection...that is about it...nothing serious at all. This is from well over 1,000 sessions with working girls throughout my lifetime.
You are quite safe, please do not worry and overthink things.
