I think the odds that you have herpes are way less than 50-50. Way less. I’m a little confused about where the dots are. First you said they are on the head of the penis and then you said they are by your stomach? are they in your pubic hair or on your penis?
Without knowing too much more, the odds of getting herpes at a single encounter are very low – not impossible but low.
Have the dots been around for quite a while? I’m having a little trouble following your timeline. Herpes lesions would not be around for more than a couple of weeks.
