The first rule of Masturbation Club is how you masturbate is up to you. Your body, your choice.
And it’s true that masturbation looks very different for all of us; some of us may be pillow-humpers, some of us may enjoy penetrative sex toys, and some of us may just enjoy some spit and our own hands.
The second rule, though, is masturbation can be fun when it’s mutual!
Before you ask, yes, mutual masturbation is different than having sex with a partner—even though it is just as fun!
