I feel badly for you if your experience with arousal is limited to sexual expression only. I think that is what this woman is working toward understanding, how this life force impacts all of life, not just what happens in the bedroom.

It's sometimes taken for granted that a person who masturbates often may be doing so for stress relief caused by non-sexual circumstances but if someone gets the idea to explore this dynamic from the other end, it suddenly becomes something to make fun of or disparage out-of-hand (pardon the pun)?
