(IMG:style_emoticons/default/oops.gif) Greetings

This is rather an odd question (for me to ask anyway). Bit off the beaten track for my threads anyway. But here goes. (IMG:style_emoticons/default/baby.gif) What belief systems, magical methods involve the digestion of male semen? What are the desired effects? What are the psychological effects on a male priest who digests his own semen or another's semen? What are the viewpoints towards this priests sexuality?

I know male semen is an extremely powerful magical tool. A very powerful magical talisman. (IMG:style_emoticons/default/face08.gif)

I'm not about to embark on such a knife edge path. I just need to understand the magic system and tradition behind such a ritual.
