My first day fishing with a Sexy Frog and nothing happened.

The fish didn't find it Sexy or appetizing.

Strangely enough though, other frogs found it sexy.

I casted to a far bank, in the middle of some scum and I saw instant movement about 30 feet away. 

A bull frog was making for my bait.  It was a good learning experience watching a living frog move with purpose.

By the time I was done I drew two frogs to my lure, but no fish. I kept wait for one of the frogs to be swallowed, and hoped it would be the sexy one!

Alas, any sex appeal was limited to the bullfrogs.

Bullfrogs love to eat other frogs, real or fake. They can be a real pain if you get in an area with a bunch of them, and bass really don't mess with big bullfrogs very often in my experience but prefer leopard frogs and other smaller frogs. 

Lol you reminded me of the song chrome by Montgomery gentry

I've seen big, and mean big, bass crush a bullfrog at my frogging hole.  You're fishing the right location when frogging and bullfrogs are present.  It seems that during twilight is when the big fish become active and actively roam the shallows looking for a big meal.  I bought a Spittin Wa 70 and am taking a serious look at some of the pike and musky sized frog soft plastics after setting and breaking my personal best three times at my frogging hole lats summer.  Big bass east bullfrogs.
