Is vaginal tightening surgery very noticeable?

I'm concerned because my husband's reaction during intimacy isn't what it used to be.

When I subtly brought up vaginal fillers, he said he didn't like the idea, thinking it would look artificial.

But you know how husbands often dislike breast augmentation at first, only to love it once it's done, right? lol

I feel like he'd like this a lot more if he tried it, but is it possible to get it done without it looking obvious and naturally?

I've been looking into it and found that many people at Golden Balance get vaginal fillers after childbirth (natural birth), just like me. Did you tell your husbands?
