I wasnt sure where to post this query, I hope someone can point me in the right direection...

Firstly Hello my name is mahreen, I am UK trained nurse relocating to NJ.

My passion is sexual health/Gum... however I am under the impression no such medical speciality exsists in the US? I am not at all certain which specialty Sexual health clinics would come under in NJ. I would be forever greatful if someone could inform me as to the best path in pursuing this speciality and wheer to look for related jobs.
