Eau De Rourke?

"The smell of rotting eggs gives men an erection."

Yup.  The article over at The Sun goes on to inform us that "A gas called hydrogen sulphide - also released when eggs rot and from the exhausts of cars with catalytic converters - is given out by men just before they have sex."

Awesome.  We say bottle that sh*t up, slap a celebrity endorsement on it (here's talkin' to you's alls), and you might have yourself the world's best-selling fragrance.
