Firstly, I want to say I'm sorry for everyone who has had bad experiences like the ones shared here, and thank you for your courage.

As for me, I cannot say that anything from my childhood has resulted in me being into BDSM. There are some moments few and far between, in which I had interacted or saw BDSM type things. Such as tying to a chair like flying66 mentioned. I would say these experiences made me excited and left me feeling hot (in that kind of way), and I wouldn't say there was any dramatic experience to note, however.

I would not try and say that your past experiences couldn't be why you're here, but I would like to say that I'm not sure that they're directly related to why you're interested in them. Personally, it is my opinion that we're born interested, although it may take a while for people to realize this.

In your case, I think it would be best to go slowly with it. If you find that it is a good outlet than do continue with it. I'm very glad you shared this with your husband, and from your description he sounds like an understanding person. Please be patient with him though. He, like us, cannot fully comprehend your situation and I ask that you take the time to understand that he only wants the best for you.

Best of luck.
