On a related note, Smilingbill12 did a great review http://eccie.net/showthread.php?t=723749 on doubles that raised some similar issues. Doubles has been a fantasy of mine for quite a while, probably true for many guys. My question is what is the standard (if there is a standard) protocol for doubles? Is there girl on girl play? Is switching off allowed? One and done or the time period?
