Any suggestions?

My husband wants to try bdsm ive read books on it n i love anal n being choked. But thats all i really know.im willing to try because like im a boss. Im a big sister so ive ALWAYS been in charge. Even in a few of my relationships ive always told them what to do n how to do it. Always on top n everything. So im excited to try it but extremely inexperienced and have no idea where to start. Any suggestions?
