I recently read about a fish where the male subsumes itself into the female and becomes merely a pair of testes that feed the ovaries or something. Does anyone know anything about this weird fish?

About a year ago I was diagnosed with epidydimitis, which has become a chronic (but low-level) pain. I am now interested in having a child (to be precise: being a sperm donor for a close friend; not via a clinic).

I'm throwing a Balls Ball. You know, just a buncha dudes, enjoying balls, watching 300 and drinking together. That kind of thing. We have a reasonable menu already, but still, I would like you to suggest your favorite balls. Give me your balls. [more inside]

BallsFilter: Why is male semen best created and stored at temperatures below normal body temperature? Why keep those delicate ovoids outside the body where they're exposed to a good swift kick? Shouldn't they be tucked deep inside for safety?
