Wow! Hard to build trust back up after he failed that kind of test.

Here you are, offering him what most men can only fantasize about; having a woman who's so open minded sexually, but also so extremely willing to please.
Like you, I've been much the same way throughout my years, and have always seemed to run into that kind of man, (for whatever the reason it IS that they are like that.....It's almost as though, BY providing them what they actually do fantasize about, there is no .....'challenge" (?) remaining?...who knows. I've always wondered that, myself).

Yet, what you've provided isn't enough for him? Makes me wonder what's REALLY going on with this guy....Hmmm. Perhaps he has a need to be promiscuous...as though it's an uncontrollable impulse of his? Hard to say, and even harder to find faith in.

Maybe, allow some time to pass, and again repeat the same test on the sly, (see if he passes it the second time, but not until a reasonable amount of time passes...allow him to feel "safe" in his misbehaviors again).
I'm not exactly encouraging you to rely on this test to obtain trust in him. But good God, he didn't have ANY reason to fail it the first time.

You also have the option of trusting in his actions and allow him to earn your trust back that way...so long as YOU can be good with it through those means.

I'm sorry you are going through this. I hope it works out for you.
Good luck.
