I have a very helpful tip for uncircumcised males regarding smegma buildup. Smegma can have a strong odor that is very distinctive, and it can be embarrassing when in an intimate encounter. It's pretty well known that uncircumcised men must keep the area beneath their foreskin clean, but it's my understanding that smegma buildup (the odor, not the physical buildup itself) is not necessarily an indication as to whether your foreskin and glans area is "clean" or not.
I've been masturbating about 3 times a day for 5 years or so. Ever since I first ejaculated (it took me a while to realize it was a feature of masturbating), I've been eating my semen. The flavor varies with the diet. With meats and such, there is a salty or almost buttery taste. With fruits, well, my favorite, it's a sweet sensation. Caution though, vegetables can be bad depending on what they are. But fish is the worst. Never again will I eat my semen after eating fish. I've also figured out texture can make the difference.
