Gasket or Seal Issue

Hey Experts,

As suggested by most of you, I used Plastic dip to provide seal for my tube. Its working fine, but even after providing with enough lube, most of my pubic area skin gets sucked in. So after the pumping the skin kind of gets sore & is painful.

Is there any other king of gasket that I can fit onto my tube to provide extra cushioning so that it doesnt hurt. I have also seen you posts on some silicone seals, but I cant afford that, its too expensive, any thing else close to that which you guys are using.

Thanks

I did go to home depot & ask them for the coupling, they didnt seem to have it, I also searched the web for the product number specified, but didnt show up.
