Whatever your gender, you can use internal condoms to protect against STIs, including HIV, during anal sex.
There are two ways to do this:
Wear it like an external condom
Put waterbased lubricant (lube) inside the condom and place it on the penis.
Put plenty more lube on the outside of the condom and around the anus before inserting the penis gradually.
Putting the condom in the anus before sex
Use waterbased lube around the anus first, then squeeze the inner ring of the condom to form an oval shape and push it into the rectum.
Put your finger inside the condom and push it as far up as you can. The outer ring should stay outside the anus. Do not try to remove the inner ring, you may break the condom.
After sex, when you are ready, withdraw the penis. Then twist the external ring a few times and gently pull the condom out ensuring no semen is spilt.
Make sure you use plenty of lubricant during sex because the anus doesn’t create its own.
