Most brothers here will ask, "What's the purpose being used for the SiliSleeve2?" This matters quite a bit.
If you're using the sleeves for all day stretchers and traction devices, you definitely need a smaller diameter to the
sleeve tightness can hold onto your skin to prevent sliding. Let's use the 4in flaccid penis as an example. Remember that you should be measuring the flaccid girth between the base of the glans and 2in below the base of the glans. This is where most of the traction for the
sleeve to work in prevent sliding because of the foreskin or the penile shaft skin.
When you're flaccid, it doesn't mean there's an absent of blood volume in the penis. This is partially expanded penis. When the penis is relaxed further, you'll lose that extra flaccid volume. Under compression of the
sleeve, it may reduce down to 2.75in instead. When the penis is a cold environement, it will shrink even further. So, how will you test the true state of flaccid? Squeeze the penis as hard as you can and drain as much blood out of it as you can. The smallest circumference you get from the squeezing is your true flaccid circumference.
If you're using the
sleeve for anti-turtling, you can use the SiliSleeve2, but you can use a looser size. This allows you to urinate with comforts, while preventing the penis from turtling. You will need a piece of stabilizing wrap, like the
TheraBand, you prevent the foreskin from causing that retraction. I wear the SiliSleeve2 from time to time to prevent turtling, but I need the
TheraBand to stop the foreskin from causing the retraction inside the loose
sleeve.
Hope that helps.
