[Question #2382] Frottage / genital grinding

46 months ago
Hi Dr.,

I visited an Asian massage place and did something stupid again.
At the end of the massage the lady got nude and climbed up to straddle my waist.  She put both hands on my penis at the top and masturbated me while she was grinding her genitals against my scrotum and penis.  There was no penetration into her vagina, but I'm concerned her fluids may have gotten into my urethra.  My penis was uncovered.  Lasted a couple minutes before she  climbed down and finished me with her hands.

1. Do I need to be concerned with HIV in this case?  

2. Is it safe to continue unprotected sex with my regular partner?

Thank you.

Welcome back to the Forum.  I will be addressing your question.  The exposure you describe was a no risk event with no risk for HIV or bacterial STIs such as gonorrhea, chlamydia, or NGU.  I would not be worried and see no medical reason for testing related to the events that your describe.  Despite the fact that your penis was close to her vagina and vaginal secretions, the likelihood that her secretions entered your urethra are miniscule.  Further, please remember that is far more likely than not that she did not have an STI to begin with.  Personally, I see no medical reason to worry about the encounter that you have described.  

In answer to your specific questions: 
1. Do I need to be concerned with HIV in this case?  
No!

2. Is it safe to continue unprotected sex with my regular partner?
I would not be worried.

Thank you Dr. Hook.

To clarify, it was more than close to my penis, she ran her genitals up and down the shaft all while avoiding the tip entering.  I even told her "no inside" to which she agreed; definitely no inside.

Am I correct to assume that if her fluids did enter the tip of my penis that I still should have no worries and your answer stands?

I'm given to understand that the penis must enter into the vagina  for hiv transmission.

Thank you again for all you do here.

I understood what you meant with your initial post. No change in my assessment or advice.  This was a no risk encounter for HIV risk.  EWH

Dr,
May I ask if you can explain why it's no risk?
Is it because the fluid transfers must take place inside the body?  Or is it because we assume no fluids got into my urethra?  If fluids did enter, but happened from outside contact can they transmit STI / HIV?

Also, should I be concerned about any skin to skin sti?  She was quite particular about any touching; made me use hand sanitizer so I'm guessing she has no issues and wants to remain that way.

I guess this will be my last question if you can kindly answer.

Thank you again.

Different skin surfaces are more or less easily disrupted by the friction of sex and thus are more or less easily penetrated by HIV and other STI pathogens. The epithelial surface of the penis is composed of many layers of cells which resist penetration.  In contract the epithelium of the urethra, inside the penis is very thin and thus is more easily penetrated. 

Skin to skin touching- mutual masturbation, body rubs, and frottage is not a recognized risk factor for HIV or other STIs despite years of study.

As you point out, since this is my third reply, this will complete this thread which will be closed in a few hours.  EWH
