I absolutely disagree. I caught it the same way you did. And I almost gave it to someone the same way. I believe it definitely is an STD that is caught orally - or how else how can one descibe it? I also get it on the tongue and inside mouth (Stomatitis). Medical experts failed to diagnose the causative agent or help me at all. The experts told me I had Stomatits. Duh. (I wanted objective scientific evidence of a specific infection or agent.) Please post what your doctors discover - as it may help me or others.
I find the best treatment for me is to rinse the mouth or brush the teeth with Arm and Hammer baking soda. I can make the syptoms go away by using l-lysine (or Herpancine which contains l-lysine.) L-lysine is available at drug stores and is cheap. I avoid all acids and L-arginine as they make it worse. I therefore suspect herpes. You may discover a better solution.
Of course you may have something different than me.

Neither herpes nor any ohter STD can cause symptoms within a few minutes. Your lips obviously were irritated chemically, or by an allergic reaction--e.g. to a perfume, spermicide, etc. You don't need to worry about having anything you can transmit by kissing.
People already infected with HSV-2 cannot catch it again; or if it happens, it is very rare,
An anti-herpes drug would be silly. If your symptoms persist, see a health care provider. But put herpes out of your mind as the cause.
Good luck-- HHH, MD
