What a dicotomy you present! I'm impressed with the way you've chosen to view this and that you kept the EC in the process. That is huge!
I'm one of the millions of guys you suspect would be turned on by the legs in my lap with accompanying show. You're left wondering why your H isn't turned on enough to act on it.
But not all W have been conditioned to think that shaking their booty makes them irresistable, dear. My W would do the leg drape (without a hint of show) and be put out to think that it did turn me on. Her thought would be, "Gosh, can't you just simply rub my legs without turning it into a sex act?"
Mike - wishing somebody had taught me a lot more about W as a teenager
