SO has Retroactive Jealousy - should I tell him more truths?

Hello all.

My SO has pretty bad retroactive jealousy, probably made worse by the fact that I trickle-truth told him about my past sexual experiences - at first I told him 20 people (I was drunk and hadn't counted so I guess I overspeculated..) when in fact it was 10. His reaction was so bad after a while, when I told him the actual number he wanted to know all my experiences and who and when. This then became an obsession where he felt he would calm down by knowing more details, which would then only send him into a deeper hole.
I told him a while ago that he doesn't know all my sexual experiences, but he does know the ones I actually 'slept with'. He said that's okay, but I sometimes think about it and am conflicted whether or not I should share it with him. He's been doing better at the moment and I have read that knowing more, retroactive jealousy gets worse. The less they know the better. But I don't want him to find out and then feel lied to. What do I do?
