This is the third profile I've created on B2W. I've deleted and changed passwords because I don't want this to be a part of me but I can't stop thinking about it.
houston, you need to quit beating yourself up over what you perceive to be an addiction. Lots of us have an insatiable need for sexual stimuli of some form. I think the main concern(s) would be if your interests interfere or carry precedents over constructive, normal day activities, like your job, your affections for your spouse or gf, or other key responsibilities, or, if your interest does harm to others.
What you might be calling an addiction could probably be nothing more than sexual frustration over what you desire but aren't getting. Having just glanced at your other 2-3 posts, I'm thinking that you're wrestling more with your sexuality than with black2white porn. You announce that you're straight, but I don't think you're being honest with yourself. Plus, you've allowed your own paranoia to set in ... tell me I'm wrong, but you practically read like a book to me.
We all have mailboxes here ... if you won't discuss this publically for all members to read, maybe you could select a couple people, here, you feel you could discuss your "real" issue that's bothering you.
Welcome to b2w, and I hope you're able to get some reasonable comments and suggestions. Start by being honest with yourself, however. Possibly stand in front of a mirror and write down the thoughts that come to your mind as you look into your own eyes. Hope someone, here, can offer you some resolution ...
