The supplements that are effective have already been mentioned by other people posting on this board numerous times.

The first thing that is important to increase the sensation is Lecithin. My experience with Lecithin is that it changes viscosity and intensifies the orgasmic experience.

Arginine and a couple of other things will help erections. Another thing is that there is a newer NOS formula that also will intesnsify the erection. Not all of these will do so, but a couple of them will because they contain an agent that keeps them more active in the erection process.

References to which ones can be found on the net.

The final thing is to drink far more water than usual if you choose to go for enhancement of semen or seminal fluid. You need to increase this one vital thing to give the body more to build from.

Most of the formulae that I have tried sold in combination have proven to be "junk" and a waste of money. You can build a more effective combination yourself for less money by doing some great shopping both on the net and your local supplement store.
