I used to be really into kinky stuff. I'd want my boyfriends to tie me up during intimate acts, though we never did. Now, the idea of being tied up or held down for anything sexual scares the crap outta me, having actually experienced assault. Sex needs to feel 100% safe for me. Even without bondage, even with the man I love, intimacy can be frightening.
Maybe that's why I like shampooing so much now, it's not scary. It's romantic, and sensual, and it's sweet to be pampered and feel so taken care of.
Anyway, sometimes being tied up and forcefully shampooed. Not sure if I'd actually like it, but it's certainly an exciting fantasy.
