Hello my name is Dave, I'm 38, single and I've been a switch for well over 20 years. My experience has gone through a number of experience and changes over the years but here's a short run down:

Between 86 and 90 I had two different subs that I Dominated off and on. Also I submited to an old gaurd gay woman for about a year.

Between 91 and 95 I was in a long term relationship in which we switched roles or played without roles. Though it was a more conventional relationship a majority of the sexual activity involved some form of S&M or role playing.

Between 96 and 2000 I had at least four sub that I trained off and on and submited to Doms. Most of these were short lived only lasting 6 to 8 months.

Between 2000 and present my career and fatherhood took up a great deal of my life and BDSM took a back seat. Though I have trained five sub it was mostly through orders outside of scene and was more of a "play" situation. There has been also 3 Doms that I've scened with not more then a couple of times.

That's the basic. I could go into detail but it would take hours.
