In 90% of cases, the body’s immune system clears HPV naturally within two years. But, sometimes, HPV infections are not cleared and can have HPV even if years have passed since he or she had sexual contact with an infected person.
So it is best to have protected sex with your girlfriend.
The methods of treatment for HPV are many. several medications(like podophyllum resin, Podofilox (Condylox), Trichloroacetic and bichloroacetic acids, Imiquimod 5% cream and interferons) are available, which can be applied directly to the surface of the warts. Other treatment options include electrical cautery, surgical removal, Carbon dioxide laser treatment and electrodesiccation.
Burining at the tip of penis can be due to STD’s. If STD is totally ruled out, then the tingling you feel at the tip of penis can be due to an allergic reaction (say to body lotions, condoms, soaps etc) or it can be a skin condition like eczema, dermatitis etc or it can be a fungal infection. Other than that it can be a simple bacterial infection or balanitis.
There are many causes of anal itching apart from warts. it can be from eating spicy foods, irritation around the anus due to frequent watery stools, poor hygiene, skin tags, anal fissures, bacterial infections, fungal infections and parasitic infections. Exact diagnosis can be confirmed only after examination of the area.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
