Anal sex is an act between two consenting adults, where the anus is stimulated in some way.
The only reason you should have anal sex is because you really want to. All sex acts require full consent from everyone involved. Any response other then an enthusiastic ‘yes’ is called non-consensual sex. That’s illegal. Read more about sex & consent here.

If you are wanting to have anal sex, use barrier contraception to stop yourself from contracting a sexually transmitted infection. It’s also important to make sure that you’re getting regular sexual health check ups at your local sexual health clinic.
If a vagina comes in contact with any of the bacteria from an anus it can cause a yeast infection (thrush) or an UTI. Make sure to keep anything that has been in contact with the anus away from the vagina. If you don’t, you or your partner might get sick.
