Welcome to our Forum.  I can help you with information regarding your risk for STIs- there is none.  Masturbation is safe sex without any risk for STI acquisition even if the stripper did have an STI of some sort (most commercial sex workers and exotic dancers do not have STIs).  Much to many people's surprise, this is true even when participants in masturbation get one another's genital secretions on each other in the course of masturbation.  There are no situations in which the transfer of genital secretions from person to person on someone's hands or through clothing (even clothing that it wet with genital secretions) has led to transmission of infection. 

Thus, ALL of the events you describe, mutual masturbation or her handling your penis after touching her vagina were no risk events and no testing for any STI was needed.  The testing that you got at one week is reliable for gonorrhea and chlamydia as well, further confirming what I have just told you about the absence of risk.  There is likewise no need for you to abstain from unprotected sex with your girlfriend.

I hope these comments are helpful to you.  No need to worry, no need for further testing.  EWH 

Fatigue and malaise are not signs of the ARS.  On the other hand, your symptoms are absolutely consistent with the fatigue that often accompanies heightened anxiety. 

My appraisal stands.  The activities you have described put you at NO risk for HIV or other STIs.  EWH
