Could V Shaped Infection In Public Area With Soft, Red, Inflammed Follicles With Puss After Sexual Contact Be Folliculitis?

I had sex less than 2 days ago and was wearing a condom successfully. I did not stay fully aroused long enough to finish, but there was some grinding as the female was on top for about 5 minutes. This is how I contracted this Dermatitis as it is a V shaped infection of pubic area affecting only the hair follicles. About 30-35 follicles on each side of the V shaped area. The infected follicles are not deep and are soft and burst quite easily.

I immediately noticed the folliculitis and small infections the next morning, 15-16 hours after sexual contact. The follicles looked very red and inflamed and within 3-4 hours began forming the white-heads/ puss. I have never had any type of infection or infestation of any sort before. But I heard from a friend that I should apply Permetherin cream 5% immediately just in case. So I did this and washed it off 12-13 hours later which was late this morning..
I have searched for any type of lice without finding anything with nit comb. Just in case I washed and dried clothing on high heat cycle for 45 min. I think this is foliculitis, but not sure. What should be my next step.
