The primary outbreak that happens usually 3-10 days after exposure will happen at the place the infection entered. The penis shaft in your case.
Reoccurring outbreaks can happen anywhere in that nerve ganglia. For a genital infection this means the boxer shorts area. Not the stomach or back.
Ok last question. Do a person breakout where the exposure happened or it can breakout anywhere on the body? Example like received fellatio and breakout on your butt or back or stomach?
Can a outbreak last month or two
Depends. Primary outbreaks usually last 10-14 days. Recurring outbreaks can last only a few days to a little over a week. That's ballpark
