A big ole' slab of red meat is just about the worst thing you can put in your blood stream before sex. It clogs your arteries and directs blood flow to your digestive system (as does any big meal actually) and away from your penis.
I don't eat a meal at all within two or three hours of having sex. If you are a younger guy and in good shape this may not be much of an issue but it will be as you age.
I bring my ATF Dark Chocolate or chocolate covered strawberries when we meet. It puts her in a very good mood which, I guess you could say, stimulates sexual desires for both of us!
