Basic Crotchrope [Level 1]
Notes and Resources:
A crotch rope can be either pleasurable or tortuous depending on the individual and how tight you tie it. They can work well as an element in predicament scenes; and one of my favourite things is to have someone wear a crotch rope under their clothing when we go out together -- when tied comfortably, it can provide a gentle reminder and sexy stimulation to gradually get someone wound up over the course of hours.
One thing some people like to do is add "happy knots" -- generally a simple overhand knot, just to bulk up the crotchrope, positioned to provide extra stimulation to key areas. I don't honestly do this very much, because it's hard to get them to stay in the right spot, but it can be good for more short, intense scenes using a crotchrope. On women, it's particularly difficult to get one to stay right on the clit and often uncomfortable if you do; you may find over the vaginal opening to actually be a better spot. On men, try the perineum.
