How to Pump Your Clit

Clit Pump and Cylinder Kit

Clever dykes and transmen have borrowed a few tricks from their gay male brethren and applied quality vacuum pumping systems to increase the sizes of their clitoris. In addition to the visual satisfactions and sensory thrills of supersized genitalia, clit pumping lends itself to gender play, SM and medical scenes, and is fun for gearheads who love the latest sexual technologies.


The entire clit pump system consists of a small clear cylinder (approximately 3/4" by 4") that attaches via flexible tube to a hand operated vacuum pump which, through powerful suction, pulls blood into the clitoris and the surrounding genital structures. As the clit, the clit hood, and some of the labia become engorged with blood you can see the clit "grow" as it is sucked into the cylinder. The intense tugging sensation is enough to generate an orgasm for some, for others the goal is to produce a clit big enough for penetration, and for others, the thrill is in playing with the swollen and sensitized tissue after the cylinder is removed. The intensity of the sensation is not for everyone. Here are the basics on how to do it:

  • Get good equipment and familiarize yourself with it. Expect a high quality pump and the Pyrex cylinder to go with it to cost upwards of $100. Cheaper options exist, but they don't work as well. Practice using the pump on your thigh and make sure you understand how it works, including the quick release valve.
  • Prepare the area. The pump works best if the tissue is already warm and has good blood flow. It helps to be turned on, to take a bath or shower first, and to shave any pubic hair that would get in the way of a good seal. 
  • Use a thick water-based lube. Maximus is one brand that will help create a seal between the flared opening of the cylinder and your skin. Coat your clit and the inside of the tube to prevent chafing.
  • Get a grip. Hold the cylinder snugly against your skin with one hand and use the other hand to pump. Once the suction has created a seal, you can let go of the cylinder.
  • Go slowly and treat it experimentally. Start with the valve open to just feel slight sucking. When the valve is closed, each squeeze of the hand pump increases the vacuum pull on the clitoris and surrounding tissue, so pause after each pump to see how it feels. Pain is a sign to stop. Don't expect to fill the entire cylinder. Experiment with releasing all the pressure and then pumping again.
  • Enjoy the heightened sensations. Stop pumping after a few minutes and enjoy the sensations or let a lover appreciate your fattened clit with her mouth.
  • Don't over do it. A little pumping goes a long way and over-pumping can desensitize the tissue. If you find yourself numb rather than super sensitive, then you'll know to do it less next time.
  • Where's the camera? The engorged tissue swelling to fill the clear cylinder will be an amazing shape, color and size, so enjoy the visuals!
  • Play around. The pump and tube can be detached, leaving the engorged clit still vacuumed up into the cylinder, where it will stay until the seal is broken (usually by pressing the quick release button). Play around with your new mini dick-gently: tug the tube, hold a vibrator against it or, if you've got someone to help out, (or if you are very limber), suck on it.
  • You can fuck while the cylinder is on. Swaddling the cylinder with a little padding to cover the valve end and then covering it with a small condom will make it more comfortable for your partner.

  • Push the edges. For those who like to inflict sharp sensations on their lover's tender parts, this is a toy for pushing the edges. And tops with butch bottoms find clit pumps menacing, technical and well suited to gender play.
  • No insta-penis! Some daily pumpers report small permanent increases over time but usually the tissue returns to a swollen but near normal size as soon as the vacuum pressure is released, and all the way back to normal by the next day.

Nipple Pumping

The cylinders used for clit pumping were originally designed for the pleasurable sensation and/or enormous nipples created by nipple pumping. If you enjoy the feeling of hard sucking on your nipples, you may enjoy the steady pull of a vacuum pump. The same basic suggestions apply: go slowly, experiment, enjoy the visuals, and stop if it hurts.
