Husband (22m) maybe sexually harassed me (22f) when we started dating. How do I cope?

My husband and I started dating at 15, then broke up, were on and off, and started dating a year later and have stayed together ever since.

He was totally normal about sex this whole time. He has an extremely high sex drive but always took no for an answer, just initiated very often. We actually don’t even have sex much right now (high stress stuff going on) and he never complains.

That said, I recently remembered that when we first started dating, we fell asleep on FaceTime once, and I woke up in the middle of the night to like soft moaning and shuffling. I opened an eye and he was masturbating, though I can’t remember if his penis was onscreen. The point is he had his camera and volume on when he couldve just turned both off. I pretended to be asleep and he turned off the sound a couple minutes later. I can’t actually remember it that well, hence the maybe in the title.

Months later he told me that his most recent ex gf would (and continued to) FaceTime him in the middle of the night with her genitals onscreen to initiate phone sex, even if he was asleep. Maybe that had something to do with it, but maybe I’m making excuses for that.

We never talked about it, and I doubt he’d remember since he has awful memory and it was so long ago. Is this forgivable? How do I cope? I guess I just want reassurance that someone could do this and still not be a monster..

tl;dr: Husband flashed me when we dated as kids. Is That forgivable?
