Welcome!
very simply put...you are who and what you are, nothing more and nothing less...as are the rest of us. we are all different and each of us has our own little niche in BDSM, everyone's kinks are different and if it is a kink that you share with others, you will find that it's by varying degrees. it's part and parcel with being an individual. that being said...trusting someone with something this personal is always going to be hard to do, for anyone. the fact that you are cautious about just handing over your trust is a good thing actually. one MUST be cautious when it comes to meeting others online...let alone when trying to play.
if you are looking to meet like-minded folks, you are in the right place. it's been my experience that most here are very open-minded and very willing to share and answer any questions you may have. the best way to get started is to simply put yourself out there. maybe look at it as just meeting others who share the same interest...nothing wrong with making a few friends before or while inadvertantly looking for a playmate. posting on the forums and maybe joining into chat in the library's chatroom are both usually a good start.
i wish you well, and hope you enjoy your stay!
