Watching a woman masturbate has been a life-long turn-on for me.

My first real GF in high school was a hot older woman--17--and she got me started on mutual masturbation before we ever had sex. I was set on that path at an early age. And I've had several lovers who asked to watch me do it--they'd never let me finish, though, they'd jump in and finish it for me. When I was young and up to about age 50 I'd spank it pretty regularly but after 55 or so, I rarely did. Just not the same drive or need. Gotta have the sight, scent, taste, feel and sound of a woman to get there, now.
