Overcoming masturbation weirdness

Hi everyone, I'd like some input on an idea.

I was raised to view masturbating as unacceptable. It took me a really long time to be ok with the idea of myself masturbating, even though it's the only way I get off. My real issue is that the idea of my husband masturbating really upsets me. I know this is something I really should get over (I should only be upset if he's also watching porn or doing it a lot or doing it when he has the option of making love to me instead but he doesn't always because he travels for work). I have been trying to think of a way to get over it and I may have thought of a good idea:

I want to tell him how I feel (we have never talked about this at all) and tell him I want to get over it. Then I want to ask him to let me watch him get himself off. I've never seen a man masturbate and maybe it would help me think of it as more normal if i have an actual experience with it

What are your thoughts on this idea? Does anyone else struggle with this?
