I'm with you foxy..at least about my body...I'm pretty sloppy with everything else. I'd let a guy do it, but of course I'd make sure I was extra clean first.
But Goblin, have you tried to talk with your wife about this? Not so much for the sex part (though it does count a great deal in a marriage), but b/c by neglecting her body like that she's setting herself up for potentially big problems down the road-> several of which can be prevented/stopped with regular GYN visits.
Good luck to you.
