Hello to all

[Chill]

Im a 31 yr old male, mostly looking for information on "how to". Ive normally been the dominant one in the bedroom, but more when it comes to control. My new girlfriend and possibly my last one has push me beyond my limits of dominance (in a good way). She has alway liked to be the submissive one, but also liked some SM vs I have not been. Im willing to try to cause her (pleasurable) pain, but Im just gonna do some research and maybe talk to some people before I jump in head first. I know the concepts of safeword, handcuffs, spanking and things like that but I would like more information/ideas. Also would like to know concepts/ideas/information on like when to push the limit and when not to, besides when she tells me to, as if shes telling me shes controlling the situation and not me which defeats the purpose. Any e-mails with experience, links or any useful information will be greatly appreciated
