I'm sorry to take a different tack on this, but ....

Please, take all of this as constructive criticism. I mean nothing derogatory to you.
Having a hall pass is one thing. This is a full blown love affair. I see no reason to believe it's anything other than that. 8 of the last 11 days you've been with him? You might as well be living with him and not your husband, and asking for a hall pass to be with your husband!
The sexual experiences you are having with this guy sound great. I'm very happy for my wife when she has such experiences too. But, everything my wife does in the lifestyle (and vice versa) are out in the open. We tell each other everything, nothing held back. If you are questioning whether or not you should tell your husband something like this, you are already cheating on him. Yes, even with a hall pass. It's cheating because you are intentionally holding back information that just about every husband in the lifestyle would want to know. You started out lying but not being honest with your husband about you having this guy in mind when you planted the idea. The lies have just continued.
It isn't about whether or not you are having too much fun. There is no such thing. Every time my wife has sex with another man I want her to have the absolute best experience she can possibly have. After all, that's the point, isn't it? It IS about that your husband is not along for the ride. Now, if he's all happy about that, doesn't care to know, etc., then fine. But, it doesn't sound like that is the case. Rather, it sounds like you know you are doing something wrong and you're very worried about your husband finding out because it might go away. Your biggest worry seems to be losing your hall pass.
I think you already know the answer to your questions. If you want to keep your husband and this guy too, I strongly suggest you STOP playing with this guy for a night at least and have a heart to heart talk with your husband. Be prepared to hear that he wants you to stop seeing this guy, and don't get angry with him if he asks for that.
