The rubber covering for penis. The holes could be a bit bigger.
I never even thought about using one until a couple of months ago. When I was badly injured in an accident back in "97" I just accepted the fact that I would have ED for the rest of my life. I never even knew these things existed up until 3 months ago. Now that I bought one with tremendous sucking power I'm hoping that in time it will improve my situation & I will no longer have to walk away from women. The part & cylinder is very easy to clean if you use a water-based lube.
I love this product! Does everything it says it does and feels great!
My first ever and I can see and feel the difference! I can stay hard for my girl and she loves it too! I also get more horny as well.
Works good and good suction power. Three rubber tips for the microman, middleman, or elmacho grande. This thing could suck the crome off a trailor hitch.
