No one wants to talk about it, but HPV (human papilloma virus) is common, sexually-transmitted, and can cause suffering and reduced quality of life. This is serious stuff, and you should take a moment to think about it now.
Life is full of too many great experiences -- and orgasms! -- to live in fear. I'm happy to hear that you're proactive when it comes to owning your sexual health, so why not add getting to know your butthole to your to-do list?
