... and make a few realizations.

First off, of course the sex is great. It's sex with another man, who you have not been married to for X amount of time. It's also "forbidden" sex, so that just makes it all the better. Plus, it's sex with someone you don't know very well, giving it that mystery man element. So, of course it's going to be good... for awhile. Then the mystery wears off and suddenly he's just another person. Judging by your reactions and his, this has already happened.

So, what does he do for you? Does he respect you? Is he considerate of your feelings? Do you trust him? Do you feel like he really cares about you and your feelings?

You've answered most of these questions already in your post. You know what the answers are. So, here's the real question:

Do you feel that you should meet him again, or continue your relationship with him?

Ultimately, the decision is yours. You have to make it for yourself. We can give you advice and we can give you instruction, but whether or not you follow the advice and instructions you receive is completely your prerogative. Just be sure to ask yourself the right questions and answer yourself truthfully.

What is it about him that appeals to you? What makes you think he's any different or better than any other dominant man out there? If you don't feel he's very knowledgeable, then would a more experienced dominant not be a better choice for you? Or perhaps one that is willing to learn? Finally, if he's trying to isolate you from this community without actually knowing its purpose or trying to understand it, what does that say to you?

Answer those questions before you make your next big decision.
