This sounds like pimples or folliculitis (hair follicle infection), nothing more. Both the location (inner thighs) and your description are against both herpes and warts. Another possibility is molluscum contagiosum, a minor viral infection that can be sexually acquired--but that is unlikely. I think you have zits, nothing more, and nothing related to your sexual exposure 7 months ago.
Of course see a health care provider if you remain concerned. Good luck-- HHH, MD
