Hey Red I LOVE big an heavy women, I would love to try this with you, and if you think you are brave enough, I would even let ya step on my stomach, if you think you can. Wanna play wrestle, think ya can pin me?
First and foremost: Safe, Sane, & Consentual! Determine what appeals to you in the lifestyle, & what your limits are. Many people think BDSM is only about kinky bedroom fun, their idea of a Dominant woman is that she does all the work in the bed (which is a misconception). Read up on it, there are many good sources both online & in the bookstore (a book that is often referenced to is "Forget the Roses, I Want the Thorns"). There are several websites that let you print out or download a questionnaire for both yourself and the prospective sub. Use a search engine to see if there are any BDSM groups that meet in your area for a possible mentor. Best wishes!
