Use lube:
Unlike the vagina, the rectum doesn't self-lubricate. This is why it's important to warm up the area with plenty of water-based lube and your fingers.
Insert the toy:
The key to anal play is relaxation. There are two muscle rings known as the sphincter around the entrance to the anus. You want to be gentle with them when inserting anything into your butt. If it's your first time, just relax, breathe deeply and bear down slightly with your sphincter muscles as you insert the toy.
Experiment and play:
You can enjoy anal pleasure through butt plugs on your own or with a partner.
Solo sex is a great way to explore anal play, butt plugs make an excellent masturbation companion. You can stimulate the clitoris with fingers or a vibrator, take the time to see what feels good to you.
Many people also love receiving oral while they have a butt plug in. They are also a great way to experience double penetration: slide one in after applying lube and wear it during vaginal sex with a penis or a dildo.
Remove the toy:
To remove the butt plug, gently pull it out while taking slow and steady deep breaths, or have your partner hold the base and slide it out for you. Removal can be easier if you've orgasmed during anal play, as orgasms relax the pelvic floor.
Clean well:
After play, always wash your butt plugs and your hands with warm water and soap or a toy cleaner. If you have a vagina, avoid transferring any bacteria from the butt to the vulva or vagina or it will cause an infection. This means you and your partner need to wash your hands before you can keep going during a session.
