How to properly support performance issue?

I (41F) met a guy (61M) last weekend (9 days ago now) and we vibed a bit. We ended up chatting throughout the week and got together this weekend. Friday night and Saturday morning was no issue, then Saturday night and this morning he had some difficulty keeping hard.

I didn't point out the issue and we didn't discuss it, I just laid beside him holding him and kissing on him.

We're getting together again next weekend but I want to make sure if something like this happens again I don't do anything to upset him or draw attention to it. It really isn't an issue because he's really good at other aspects.
