I wonder if two dudleys make a studley?

two dudleys make a very boring threesum. ;)

yabbut - I mean, like if they breed n stuff??

How would you define a dudley tho? Are they a person who has had a considerable amount (not necessarily alot but enough) of experience with sex, and still just don't get it? Or do you include anyone who isn't "good" at sex, even if they are yet unexperienced or out of practice for some reason?
