That is a lovely set (tweezer clit clamp and nipple combo). May I ask where you got them?
BDSM and sex are not synonymous. Yes, BDSM scenes can and will include sexual contact of some kind, but that's really just a subset of the norm.
I would recommend the book SM101 by Jay Wiseman.
As hot as this may sound, I would highly advise against it. (I'm swear I'm gonna get kicked off this forum being the safety police that I am and ruining all the fun). Another approach is to have a trusted friend set up an anonymous rope date with a known, trusted, skilled rigger. You don't have to know this person, but your trusted friend wouldn't allow you to be in the clutches and rope of an unknown.
I mostly require safewords in role play. "Fuck you asshole, that hurts! is not a safeword there, my slutty little pet". ;) I typically do rope and negotiate with Bottoms to use real words, real English. It's vital if something is wrong in a rope scene that it be corrected immediately! I also have non-verbal cues prearranged if it's a loud dungeon. But, stoplights, G/T/R are the norm.
Wartenberg Pinwheels are great. I use them frequently in rope scenes. They can be delicate or mean. (menacing grin). Clean with alcohol between partners. (Please). I typically use them once someone is partially or better yet, fully suspended. Great across the nipples, clit, all the way up the back of the leg and up to the back of the neck. Drives them fucking insane! Test on yourself first, it doesn't take much force with these things.
