No STDs are transmitted by kissing or hand-genital contact, and the risks are very low for cunnilingus (oral-vaginal contact) and rimming. I haven't a clue what a "slap on" is, but I doubt there was any risk there. I see no need for STD testing on account of this event.
Good luck-- HHH, MD
Thanks again.
In the interest of enlightenment, a strap on is a device consisting of a harness and a dildo that a woman wears so that she can penetrate her partner, in this case anally.
I guess a "strap on" is a dildo?
There are theoretical risks for some of STDs you mention (no risk at all for chlamydia), but too low to warrant routine testing. Of course see a health care provider if you develop sores in or near the mouth or a sore throat. But really, you have little to worry about here.
Sorry, typo..."strap on."
I had read that cunnilingus and rimming put one at risk for herpes, HPV, chlamydia, and gonorrhea, among other std's. Glad to hear that my risk factor is relatively low.
Thank you for your prompt answer.
