Has anyone’s husband had trouble with ejaculating and feel that it’s maybe contributed some to infertility?

I have PCOS and I don’t ovulate. I have taken 6 successful cycles of clomid and we still haven’t gotten pregnant. He has ED issues due to porn he watched frequently before we met and during (he’s working on that part) but I’ve never seen him actually ejaculate and have never felt him do it in me or seen him orgasm during sex. I’ve sometimes seen cum on the outside of my vagina when we’ve finished but not much and many times I don’t see any evidence. He’s the only man I’ve ever been with so I don’t have anything to compare it to. Anyone else experience this?
