I would suggest going back to see your Dermatologist on this .... no STD symptoms would last 7 months straight!

Herpes doesn't leave scarring to my knowledge and developing symptoms one week later seems way too soon for another outbreak. Your doctor is probably right that you have folliculitis, but seek the opinion of another doc if you remain concerned. However, since you had unprotected sex, testing for STDs is a good idea anyway.
Good luck,
