1). Only one position at all?!?!? Variety is the spice of life.
2). Domination? Just her doing her bloody job. Why should the man have to do all the work?
3). I don't necessarily see her breasts. There are so many other positions with her on top like the lazy truman, the lady godiva, the free love ride, the "ringling brother and sister and barnum & bailey circus" (even though that one's a b1tch to pull off), the lego my ego, bang-gliding, the starting block, x-marks the g-spot, the ski lift, the stealth bombshell, levitating the lonely assistant, jockeying for attention, the water slide, the love montage, the papoose, the praying mantis, and........well, you get the idea.
Backwards cowgirl is the 3rd most gratifying position for women according to a recent MRI Dutch experiment so I would recommend it be at least tried.
4). Goats are dead sexay........
