I'm a punter with an interest in BDSM. Rope needs skill, takes time and is potentially dangerous. I always found the simplest things are best for shorter bookings, wrist and ankle cuffs, decent leather ones, a good blindfold and scarves for tie and tease, mountaineering clips, ball gag, maybe a hog tie. Then a selection of floggers and whips, vibrator, strap on, maybe inflatables. When I started I used to cart round a load of stuff which was mostly not used and a pain. A few high quality items and a bit of imagination are better (in my view)
