Come on,

Ambidextrous of course! It takes practice, you've seen The Rock do it many times, or body builders, they flex the pecs!..... Now flex one two three, one two three!

No, I've never seen the rock or any other builders do it. I'm all about music, not muscles. Besides, I could never stand looking at that ugly mug of his!!

I"m right-handed, sleep mostly on my left side and my left breast is the larger.

I've finally gotten to where I can flex my pecs, together or individually, right or left, without involving the surrounding muscles. It does take practice, lots of it. Now to get those pecs built up.
