Performing oral sex on your partner’s anus (also known as rimming) can be part of any sexual relationship, whether gay, bisexual or straight.
If you are concerned about hygiene, ask your partner to wash first. You could also bathe together as part of foreplay.
Your partner may like it if you gently kiss and touch the area around the anus including the perineum (the area of skin between the genitals and the anus) to arouse them before oralanal sex. You can then focus on the anus, moving your tongue around the outer area and finally inserting your tongue. Remember to listen to your partner and do what they enjoy, whether that’s licking, sucking or gently probing.
If you are giving oral sex to a woman, don’t move from the anus to the vagina as this can transfer bacteria and cause infection.
