I went to the Hassle Free Clinic last week:
Hassle Free Clinic. The AIDS test gave a negative result in less than a minute. They also tested for syphilis, gonorrhea and chlamydia, and you are okay if you do not hear anything back from them in six days. For cis men who see SWs they recommend HIV tests once a years, and every three months for the others. You can also see a doctor to get your junk checked (I am fine). You can talk to a counselor if you have any concerns. It is a well run non-judgmental place. You do not make appointments, just drop in. I only had to wait about 20 minutes. I recommend going there for anyone who has BBFS occasionally.
PrEP (used to prevent AIDS infection) and DoxyPEP (DoxyPEP is a post-exposure preventative treatment for syphilis, chlamydia, and gonorrhea. Think of it as a morning-after pill but for bacterial STIs instead of pregnancy: take one dose after a condomless sexual encounter to greatly reduce your risk of contracting bacterial STIs) are available there.
I was surprised to find out that some SWs who provide BBFS are on PrEP and/or DoxyPEP - note that that protects them, not you. I found this out from another member, who got close to an agency girl.
I should have gone there long ago. I will now go there every three months, as they recommend. It is less embarrassing than getting my family doctor to test for STIs.
On a different subject, I noticed that one SW I have been with many times is never on her period. Apparently there is a form of birth control pill that stops periods. I found this out from a different member after talking about the SW.
