We are with our man pieces for a number of reasons, one of which being his own attached man piece. So it makes no sense for us to use a dildo that lacks character when he is away. We prefer the Dilly we made when we used Clone-a-Willy ($38). It's a little complicated to use so make sure you are around to keep him "up to the challenge" while the mold sets.
A not-so-little hint: have your mold model slip on a ribbed condom before saddling up to the cock copier for an added "Is that a banana in your pocket or are you just happy I'm on a business trip?" experience.
