As with all things medical, discuss this with your doctor prior to undertaking this procedure and get the facts on anal douching and anal sex.
If you’re not comfortable enough with your current doctor to discuss these issues, it’s time to find a new doctor. There are resources available to help find LGBT friendly doctors all over the US and around the world, such as GLMA, The Trevor Project and CenterLink. A comprehensive guide to finding LGBT friendly medical help is available through Healthline.
