I also wanted to ask about a small cut I had on my lip. It was just a small crack at the corner of my mouth from my lips being too dry. To the best of my knowledge, it wasn't bleeding while I was kissing the female, nor did I notice any blood or cuts in or on her mouth. But I'm concerned that an STD might be able to be transmitted via the small cut on my mouth? Is this possible, or anything to be worried about? I'm aware of the HSV virus and how it can be spread even without a cold sore being present. But I'm not so worried about the HSV virus as I am about HIV or Hepatitis being transmiitted in via the small cut. Is this possible?

However, I see that you've had several previous questions, most or all of which concerned patently low risk exposures, apparently influenced by your OCD. One of the main themes of our previous replies -- if not necessarily stated in this way -- is that STDs are, well, sexually transmitted. STDs are not simply infections that happen to involve the genital area. That's not what makes them sexually transmitted. The causative bacteria and viruses evolved to require sex itself for transmission -- not merely contact with genital fluids, not superficial genital or oral contact, and not through contaminated environments. Without intercourse -- i.e. genital contact with penetration, including oral sex -- there is almost never any risk from any other kind of exposure that might come to mind.

So with that background:  Yes, you correctly understand that the kissing, including mouth-breast contact, was risk free. And this remains true regardless of a potential cut on the lip. If you think it through, you'll understand that various oral sores like you have, or bleeding gums, or bite wounds of the cheek, and many others all are very common, occurring from time to time in all humans. And therefore there have been billions of kissing events or other oral exposures in the presence of such lesions. And still no observied risk of STD transmission.

So I see no measurable risk here of HIV, viral hepatitis, or any other STD. You really needn't worry about it. And in the future, as suggested by my opening comments, you really shouldn't need to ask again about exposures that don't involve actual unprotected sex. For all other potential exposures that might come to mind, our replies will always be pretty much the same as I have discussed here.

I hope this information is helpful. Let me know if anything isn't clear.
