Can’t feel my husband cumming?

Years ago when I used to have sex with my ex boyfriend, we’d use condoms but he would cum inside me, and that pulsating feeling when he came was just the most amazing thing to feel inside me 😍

So now my husband and I are TTC so obviously he’s cumming inside me. But for some reason I never feel it? Like I don’t even know he’s cumming unless he says so! He and my ex are really similar in size so that doesn’t have anything to do with it. So why can’t I feel it with him?

It’s just really disappointing because I feel like it’s a whole new amazing layer of closeness that I know is possible (because I felt it with my ex) and I’ve never been able to have it with him :( any idea why?? And is there anything we can do to maybe make it so I can feel it? Like a position maybe that may make it easier to feel or something...?
