Back in the fall of 2015, I gave an academic-ish talk for a group called We Are Takoma. I threw in some bonus bondage performances as it was also an arts venue. The talk explains why people engage in BDSM. The bondage performances are a sexy bonus.
The talk is by me
The first performance is by Sardonic and WigglyBunny
The second performance is by me and Greneydathlete
