Hi Anonymous and thanks for your post.
Anal warts are small warts that can occur inside and around the anus. Have you had these for a while? Left untreated they are likely to continue to grow. They're a type of genital wart caused by the Human Papillomavirus (HPV), a sexually transmitted disease. It sounds like you may already know that. Withholding information about the possible sharing of a sexually transmitted disease is not a good practice - would you want someone to withhold that information from you? In some cases anal warts may lead to cancer, this needs to be taken seriously. I suggest you contact your medical provider for support, especially if you are having any type of pain, and encourage you to have honest discussions with your partners. Good luck! Pat
