Here are the STDs that don't have a cure:
HPV (including genital warts)
HIV
HSV 1 and HSV 2 (oral and genital herpes)
Hepatitis (I believe)
Does all have cure? I think herpes doesnt but the others?
20 seconds should not be a worry. Risk was gonorrhea, NGU, herpes and syphilis.
Gonorrhea and NGU-1 week
Herpes-3-4 months
Syphilis-6 weeks
