As most mongers would like to make full use of their paid sex time with a woman, I suggest the use of a cock ring. I was introduced to them in Europe. They are quite simple silicone O rings that you buy according to your members size..erect of course. They need to be a bit smaller so that they constrict the blood and also help in shooting your load a bit later. They make your cock rock hard and the veins swell up and the women love that. You can get very cheap and good quality silicone O rings as you come down Kennedy bridge. There is a veg restaurant and along its wall sits the O ring dealer. Make a mental note of the size you need. And for God sake don't tell him what it's for. I buy a slightly bigger one for my balls too. Enjoy!!! Anyone with interesting stuff like home made sex toys are welcome to share..
