I've either been really lucky, or really open and confident in my pursuit of my lifestyle. I can honestly count the women/girls I haven't gotten into some form of bondage and tickling on one hand.
I honestly believe most people are open to at least trying things if you have a good line of communication going. People would be surprised how open to interesting, new kinds of sexual or play expression most women really are.
I think back to a time when I was 16. The girlfriend and I were fooling around in the dark in my room and I just said to myself "screw it, I'm going for it." I had my girl sit up, kissed her neck a little and told her to put her hands behind her back. She did, and I tied her wrists together with a bandana I had. She says "Are you tying me up?!?" I just go "Mm-hmm" and she's fine with it. It was fun.
Laid her back, kissed her some more, started playing a little and then started tickling her lightly along her side. Rather than freaking out, she just starts giggling and jokingly saying things like "Oh, you're cruel!" Over time, we expanded our play by just doing it. Next time we were together I had her tied to the posts of the bed.
Point is, I think a lot of people are kept from exploring their fantasies out of nothing more than fear of what someone might think. I've always suggested to people to just be honest. If you have a relationship going with someone, the worst that's usually going to happen is that person's gonna say they're not ino it.
Just don't make a big deal out of it. Tip: Go for the bondage first. Most people are more familiar with and willing to try some form of bondage with a lover or partner. Rather than sitting down and going into the whole spiel..."Ok, I...ummm...have this thing...I like to...ummm....tie girls up and...uhh...well, I liketoticklethemifyou'dliketotrybutifnotit'sok"...just wait for things to get a little hot and say something like "Wanna try being tied up?". If she's good with that, just slip the tickling in once things are set and gauge the reaction then. If she freaks and is obviously NOT going to be into it, it's easy to just say "Oops, sorry, didn't know you were that ticklish". If she laughs a bit and you're on the fence...just kinda hold her gaze like a challenge or something, make a "moment" out of it. Like "Oh, we've discovered something, have we?" See where it goes from there.
