In my speech 1A class I am doing a group presentation. We chose Gender Identity and Sexual Expression as our main theme, and each of us is presenting a different sub-topic.

I am doing BDSM.

What I present about BDSM has to be tailored to the needs of my audience, which is my Speech 1A class, the mode age being 16-20. I have to assume that my audience knows little to nothing about BDSM.

This opens the door to a wide range of topics within BDSM that I could talk about. However, there is so much about BDSM that I could talk about--and I only have 5 minutes 30 seconds to speak--that I need to limit myself to one or two aspects of BDSM.

One idea to help the audience relate to my topic is by discussing 50 Shades of Grey and separating the fantasy of the book to the reality (because the book has very little real BDSM in it). Another idea was to discuss consent and safe sex, which is one of the more important aspects of BDSM, but I don't know how I'd be able to get the audience to relate to that.

So my question is what you would like to know about BDSM that you don't know already or what about BDSM might be good to talk about? Thank you.
