Muffing

Muffing is a sexual technique for manually stimulating the inguinal canals, interior passages within the groin located behind the scrotum and testicles. In fact, the testicles descend from the inguinal canals, and trans women sometimes tuck their testicles into them, allowing them to "tuck" their dicks. Although the inguinal canals are covered in flesh, they can be penetrated from the outside, providing pleasure to the receiver. Although muffing is pleasurable, most people say it is best as a form of sensation play or foreplay, not a path of orgasm.

While the term was originally described to give pleasure to trans women, men could also enjoy muffing. However, for them it won’t be used as a substitute for the fingering that people with vaginas enjoy.

More About Muffing

The technique was first described by Mira Bellweather in her pioneering zine, “Fucking Trans Women.” As a trans woman with a penis, Bellweather's zine focused on pleasuring pre- or non-op trans women, rather than post-op trans women. Muffing can be a masturbation technique or something someone does to an intimate partner.

Muffing may involve inserting one or both fingers into the inguinal canals. Locating these canals can be difficult, as they’re surrounded by flesh. Bellweather suggests people can find the inguinal canals by feeling upwards and behind the penis. While the entrances are small, roughly the same diameter as a finger at first, they will stretch with repeated muffing. As the inguinal canals are so small at first, newbies should start slowly and take care.

Muffing feels good because the canals contains the ilioinguinal and genitofemoral nerves that make touching your genitals pleasurable. The deeper a finger is inserted, the better it should feel. However, you should avoid fingering too deeply, or you could potentially cause harm. There are also psychological reasons why pre- or non-op trans women who feels no real connection to their penises often find muffing sexually gratifying. Some trans women who get gender reassignment surgery say they miss muffing because fingering the vagina, which is naturally lubricated, can be much messier.
