I have great hopes of one day becoming the Sexual Kung Fu Master Edge Lord and be able to edge non stop for 90 days straight! Without food or drink I will be able to absord the sexual energy of sluts everywhere to fuel my tremendous sexual power. Then on the 90th day I will blow a wad so big that all the sluts of the world can enjoy;)
For real though. I do think this is a great practice and sexually can give you a lot of staying power. It also can give you better self control mentally as well.
