Shit on his dick in anal

I was doing anal and when he pulled he had shit on his dick.

He just kind of jokingly said “don’t think that was a good idea”

We shagged after.

But it’s a fwb situation apart from we dont talk. Should I message him and be like “sorry that happened it won’t again” or something. Or should I just leave it?

Like how disgusting do you think he will have thought it was?

* it’s the second time we’ve done it, it was fine the first time but t came as a surprise this time so I hadn’t prepared
