Have you guys read the liquid lapdance thread? It included the suggestion below!
"I have a simpler system. I wear a condom that is lubed on the inside and held on with a rubber band that is twisted in a figure eight shape with one loop under the balls and one around the base of the condom. I can cum easily. After trying different lubes I found the liquid ones tended to leak out, so now I use vaseline with a non latex condom. The FC2 female condom made of nitrile works well, is easy to put on and is very durable. I also wear King Style underwear with an open top to hold me in an erect position."
I don't know about putting a rubber band around my balls! Or Vaseline on my dick! Seems non-brilliant to me! What do you guys think?
