I profited greatly from reading Akasha back when she was active on usenet (or Google Groups as many people now know of these discussion forums). Her guide is a classic and I quote words certain men should keep in mind when seeking to encourage their wife or girlfriend into female dominance:
Your fantasies may include chastity devices or more severe treatment or humiliation regarding your inability to have release. Back off. This is about having her enjoy the concept of controlling your pleasure, and she must start with what is fun and not complicated. Chastity devices can be expensive and bulky, and in practice are often hard to implement. If she really enjoys controlling you verbally, she may go down that path, so make sure she has fun. Men are often tempted to create their own rituals and rules regarding “not being allowed to cum” because they have done it for so long all by themselves with a make believe femdom, or someone they met on the Internet. DO NOT try to mold your mate into this person. Let her find HER style. Got it? Bottom line again — let her find out what works for her!
