Tips on improving vaginal toneness/resistance

So, I’ve been in my head a lot about my vagina possibly being too weak. My husband and I have been together for almost 7 years and he just told me for the first time a few weeks ago, without me asking, that I was “tight” during some fun sexting. I’ve been wanting to hear that from him for a long time and it made me feel a little bit better at the time, but I still feel like it leans to being a bit weaker.

I don’t have bladder incontinence at all. No issues holding it and no sudden urges of feeling like I’m going to bust.

But during sex, I don’t feel as much friction as I’d like to, and my husband isn’t very well endowed. (Though, yes, I can feel it just not as pleasurable) And when I do a vaginal resistance “test” by inserting a couple fingers and pushing on the walls, my bottom wall seems very resistant and taut, but my top wall gives a little easier. When I do the kegal test by inserting my index and trying to contract those muscles, I feel my walls move a little, but they don’t “squeeze” hardly at all. I believe I’m doing them correctly.. I’m not flexing my stomach or other muscles when doing it.

I just want to strengthen it up down there so that I can squeeze my hubby down there during intimacy and so that I can possibly try having more pleasure during penetration, too. (I’ve never had an O from penetration, only clitoral)

So anyways, what’s the best way to get into a kegal routine and do you have any tips on how to make it a habit of doing them daily? How do I find the best kegal workout for me? How do I know if they’re being performed right?
