Hello,
Since it is related to post-sex.
1. Herpes - Genital warts (HPV) can be diagnosed by the presence of very painful blisters, sallow ulcers or red base.
There are treatment options for
genital herpes, but there is no cure. As to the treatment, it is based on relieving basic symptoms, early healing as well as the decrease of symptoms duration.
2. If it’s not painful- Syphilis, diagnosed by Blisters appear as the first symptoms of
primary syphilis. They usually disappear on their own with time, but remains in the body. first blisters on penis appear, important to
seek medical help.
3.
molluscum contagiosum - small, painless bumps. Need to do HIV,
VDRL, urine complete.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr S.R.Raveendran, Sexologist
