I had protected sex (condom) with a very sexually active girl. I was only in her for a minute and didnt penetrate all the way. Chances of herpes??

A minute too long. If you were exposed to herpes for one minute then you can acquire the disease on non condom protected parts like the scrotum. A; man has to ask himself a question at times like these. Do you know this woman well enough to share bodily fluids? If not, you are "thinking with the wrong brain", not the one on your but the one whose "head" gets too large" but "shrinks" from its duty post event.
