Probably squeezing above my knees, tickling my sides and biting my neck would make me tap out. Although I'd probably be laughing too hard to do much about it. Or my feet getting tickled insanely just underneath the toes. My goodness, that drives me crazy.
I think maybe start a brief conversation about what turns the other one on, and then mention being tickled works for you, but pretend it's small, so it won't be taken as a big thing.
I understand that. I've not come out about it to anyone. I don't really need to though, myself. At this point anyway. People tickle me a lot anyway. Not as intensely or as long as I want, but eh. it's something. I'm sure you'll be fine =], generally if you treat it as something small, it will be...
Even though you aren't 'into' bondage, I can't think of a way to get the upperhand unless you tie him up or something. It's not doing it for the thrill, it's doing it for the advantage. Good luck though.
I'd be fine with being tickled like that personally. But I don't think most people would be, and I totally know why. I just don't really care about it happening to me.
I was dating a girl for two and a half years until recently, and I used to tickle her every day to mess around, and she never became less ticklish. She ended up getting me a lot more than I got her, and I never lost ticklishness.
It feels fantastic, it's a lot of fun, it's a rush, and it's funny for someone to be really ticklish and then tickled. Doesn't have to be anything sexual about it.
I'm much more ticklish than most girls I know. In fact, I don't think I personally know a girl as ticklish as me. Not to suggest they don't exist, but to suggest that yes, we are as vulnerable. Though I've never been tickle tortured before.
