Naked and shy is good. Naked and shy want to please. Naked and shy, once engaged, are absolute beasts. They may not be able to teach you something new, but you can explore them and maybe teach them how you like to be pleased. It's why everyone seems to have something of a virgin fetish. Granted, getting schooled by Nancy would be awesome, too, but Nova, Luna and Annie will be greater adventures - they don't necessarily know what they want, you get to play at different things with them.
Just my two bits (not the saying, but, you know, inflation).
