I recently had a conversation with Himself about the vibrators with "desktop" chargers. I asked why you'd want your vibe out on display the whole time and said that it didn't look very practical - especially if you have kids (we don't, but still) or flatmates or even house-guests.
He said that He would find it a tremendous turn-on to walk into a girl's bedroom and see her vibrator right there by the bedside. He said it would tell Him 2 things:
1) She's has a certain amount of sexual prowess - ie, He'd probably be "in" there...
and 2) She's uninhibited by her sexuality - ie, whey~hey if He does get "in" there.
So, yay or neigh to "desktop" charging?
