I have fantasized about being tied up ever since puberty. Always a fantasy about women completely immobilizing me and having fun with my naked body. Most of the time the urge stayed on the back burner and only simmered. Every three months or so the fantasy would become overpowering and boil over for about 3 days, to a point that I could hardly focus on my work. (It must be a biorythm thing). During that time I would tie myself up by any means I could devise, and at any opportunity.
When I got married I soon found out that my wife had no similar fantasies. I figured I must be weird and never told her about mine. I never told anyone. Thank God for the internet. It helps us connect and discuss things that can't be discussed in "polite" company. Now we can get a sense of how common the feelings really are.
After 25 years of marriage, I finally admitted to my wife that I had fantasies about being tied up while a woman has her way with me. She was a little cool about the idea but played along with VERY light bondage. Over the next few years she experimented just a few times with just a little light bondage; still a little cool but enjoying it more over time.
Eventually I decided that my urge to be tied is very much a part of me and as such it should be celebrated and explored. I came out of the closet and talked about it openly with family and close friends. I also talked about finding people who wanted to explore this urge to be tied up and the cosmic feelings it releases. At that point my wife became more interested in helping me explore.
It didn't take long to figure out that, even though it was intertwined with sexual fantasies, being tied up was not about sex. It was much more cosmic and spiritual.
We also learned that being lightly tied was not going to satisfy. I had to be totally helpless and at her mercy for it to have the full effect.
She wore out on the topic much faster than I did, so it didn't intensify like I might have liked. For a while she was quite cool on the subject. Meanwhile I no longer hide my need to be tied. Our bed has a couple of home made nylon strap cuffs permanently installed near the headboard. When I am fit to be tied, I often slip my hands into them and stretch out on the bed. It is difficult but possible for me to escape only by using my toes to pry the cuffs open. If my need is really strong, I tie my feet. Then I am trapped until she comes in and lets me out.
