sizes for penis pumps

Most pumps, especially in the California Exotic Novelties line are from 2" to 2.5" in diameter. The most common size is 2.25 to 2.5"...I believe over 90% of men would feel comfortable with either size. Depending on your partner's length when fully erect, I would check under the Product Specifications download tab at link which will show the length of the cylinders....just scroll down to the item numbers that start with 1000. Be sure to read the warnings on all of our pumps regarding use, and remember that all good things stay that way with moderation!

anysize work's just make sure the seal is a snug fit for the vacume.

I agree...most higher end pumps have a flanged base, so it may be used with or without the traditional "doughnut" or sleeve on the end. The key is to use a good lube on the end of the cylinder, and keep the pubic hair shaved...this allows for a tighter, more secure seal. Be sure whatever pump is being used has a working release valve to release the vacuum if any discomfort is noticed.

how'd it work?
