My partner and I have been together for almost 15 years. We have a very healthy sex life, I am more into BDSM than he is but he's more than happy to indulge. This type of play has become much more prominent in our lives in the past 3 years or so.

We often play with me tied in bed (and reduced senses for me - hearing and sight) which I absolutely LOVE. Lots of sensory touching, teasing, etc. for a more than appropriate length of time. My hands are tied above my head and we've played around with leg restraints too, but our usual is just arm restraints.

One thing that keeps occurring is that I really struggle to orgasm if my hands are tied. Specifically, yesterday, I was tied for a long time with play and in the end I asked for my hands to be released as I was struggling. Low and behold, I had an orgasm less than a minute later, with no change besides hands being free.

Don't get me wrong, I'm fully enjoying the experience. It almost becomes like unintentional edging. The payoff is similar by the end!

I cannot fathom why I struggle to come with my arms tied. Just looking for ideas/thoughts really?
