Hello,
Your symptoms could indicate an infection, even without vaginal intercourse, as you did have
oral sex with male genitalia placed on you. Tender bumps are suggestive of
genital herpes (HSV-1 or HSV-2); you can get infected due to oral sex, even if the partner had no visible sores. First outbreaks can appear 2–12 days after exposure. HSV-1 is increasingly common genitally due to oral sex.
Other possible STDs that can infect you are
molluscum contagiosum, which appear like painless bumps, and HPV, which causes warts, often not itchy or burning.
Syphilis is usually a painless sore, less likely in virgins, but you had oral-only exposure, but it is still possible. Get clinically examined by a gynecologist or
dermatologist as you are unsure what the bumps look like. They can do a visual exam, swabs, or blood tests.
You will be told to get done STD tests also. Get them done; you will be treated accordingly with antivirals and antibiotics. Avoid self-treatment with creams until diagnosed, as some creams may worsen irritation. Avoid shaving or irritating the area.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr Nupur K., General & Family Physician
