I need to know if I need to quit BDSM, and if so then how. I actually like it as a part of my life - it appeals to my creative side, but I'm worried that I'm starting to become fairly obsessive with it, and that it's starting to slowing engulf other areas of my life.
Scattered around my house I have handcuffs, gags, dildos, butt plugs, chains, tights, a chastity belt! I've spent days modelling characters on computer software trapped in different places, I've tied myself up regularly all over the place and I've spent quite alot of money just experimenting. I have a naturally addictive personality and I'm very weak-willed, meaning I tend to get obsessed with all sorts of things regularly, but normally only for very short periods of time - but not with this. I've been doing this since the age of 11 in various forms, but it's only now I have a full and happy life it's starting to really affect things.
I have a girlfriend, who knows what I'm into, but doesn't know about all of the items I have, nor all of these practices - only the ones we've used together. Even she can't fully understand just how obsessed I can get with it - to the point where I can barely think about anything else, despite an extremely intense and demanding job. I do also keep some elements of it a secret from her - I'm quite into selfbondage as a result, and hugely enjoy the intricacies of successfully trapping myself in different positions, almost more than actually being trapped, but I don't like the secrecy.
I also don't like the way I have these massive mood swings, from nearly completely obsessed with it to suddenly thinking very clearly and sensibly, these two extremes seperated only by masturbation. Once I've masturbated, all of the desire to perform and interest in BDSM completely vanishes and I feel normal again, and it's here that I get work done, give attention to my gf and do other normal things like play music and think about generally what a waste of time the obsession really it. But then it slowly builds back up towards obsession - leading me to think it is (obviously) linked very closely to my libido and sexual drive.
Sometimes I think of putting every bondage-related into a big bag and throwing it away somewhere, but I know that my obsessed self would only go and spend a load more money buying it all again in the end. I am weak-willed and ultimately my whole life is at the mercy of this obsession. What do I do?
Thanks in advance for your help and advice.
