Curious to explore the backdoor but intimidated on where to start? We got you! With the help of our pals at b-Vibe, who make an Anal Training Kit & Education Set, we broke it down to help guide you!

First, let’s get familiar with our anus––that 1.5-inch tube that sits just underneath the rectum (the rectum by the way, connects the large intestine to the anus, and acts as our storehouse for poop (3))  and can be found between the buttocks (2). The anus is the end of the human GI tract, and serves as its exit (6); think of it like a small pipe whose purpose is to connect the outside with our inside. Both the vagina and the prostate sit in front of the rectum, and since the rectum has a thin anterior wall (2)… thin wall + lots of nerve endings = prime environment for great orgasm. For those with a vagina, this is a way you can hit the G-spot––that hard-to-locate part of the clitoris that when activated, results in vaginal orgasm and can even cause female ejaculation (7)!

The anus has special muscles called sphincter muscles. There are two types: external and internal sphincters. These guys hold the special honor of keeping the anal tube closed until it needs to open. The difference between the two? You can actually control the external sphincter by either tightening or releasing the muscle, whereas the internal sphincter is instead controlled by the automatic nervous system and it has the tendency to tighten automatically whenever something enters the anus (2). These are the key muscles to release and relax for penetration (they tend to be super tight!). We’ll get into the how in a little bit.
