Multiple orgasms for men?

But but but .... if the little head were to indulge it's insatiable appetites by pumping out more fluids on a regular basis, wouldn't the big head get dehydrated?

The brain might then beCOME a skullfull of concrete mix!

Hmmm ... it might work out ok if a hole was drilled through the top of the big head first (closely resembling the configuration on the little head). That way, you could just take a garden hose and add water after the show - (if you really wanted to restore your man's "normal" functioning, that is).
