I'm not sure how occasional it is, but I do highly encourage my sexy, slut wife.
When I first met my wife she was very sexually submissive and eager to please and be used, but was. She certainly still has those cravings and that tendencey to be the submissive, but I also progressively encouraged and challenged her for more. Each step along the way started with those uncertain anxieties and a little awkwardness, but at the same time she had that eagerness to please, as well as her becoming turned on to something new. She learned to express herself sexually, how to entice and seduce and very much how to turn guys on. She also learned how to very much enjoy the feeling of being incredibly sexy and the attention and response from the guys to it. She learned how to not just have sex, but so much more.
