Question: Are there any creams that you can buy over the counter to treat genital warts? And is there a possibility that bumps on your clitoris may not be warts ?
Answer: Not that I am aware of, but this is not a subject I am knowledgeable about.
You can get moles and pimples on the hood of your clitoris since the skin there is like the skin on the rest of your body. I believe that warts have defined edges, versus a mole or pimple which may simply be a raised or rounded area.
Genital warts, Human Papilloma Virus (HPV), has been linked to cervical cancer, so if this is a possibility you should consult a doctor.
Here are some links may be of help.
