[Question #4316] risk?

31 months ago
Hi, I am a male and recently masturbated into a woman's open mouth.  Although my penis was very close to her mouth (perhaps within a cm), at all times my penis was outside of her mouth (i.e., no penetrative oral sex).  It is possible the tip of her tongue or lips grazed my penis when she was holding her mouth open but I do not recall this happened and think it is unlikely.  What STI risk is there from this encounter? Thanks

Welcome to our forum and thanks for your question.  The events you describe should not put you at any risk for any STI, including HIV.  To expand, in general receipt of oral sex is a low risk event for STIs in general when compared to the risk for STI resulting from ano-genital or genital-genital sexual contact.  When a person receives oral sex, if they are in the minority who acquire STIs the most common resulting STIs include Gonorrhea, Chlamydia and NGU.  Other STIs are even more uncommon.  No person has ever been proven to have acquired HIV from receipt of oral sex.  In the instance you describe, there is no risk because there was no penetration.  Penetrating is required for STI transmission to occur.

I hope this response is helpful.  EWH
