Dating a Younger Guy: How Can I Overcome Body Insecurity and Fear of Intimacy?

I’m a 39-year-old single mom who recently started dating a guy who's 14 years younger than me. Initially, I was drawn to him mostly because of his physical attractiveness, but as we spent more time together, I developed strong feelings for him. Our connection feels profound, and we get along incredibly well. He’s adventurous and energetic, which matches my own high energy, and our maturity levels seem more aligned than with previous partners my age.

We haven't been physically intimate yet, but Im scared to move to that part of our relationship. It's not that I don't want to be physically intimate with him (I want to super badly!). However, Im really worried/insecure about getting naked in front of him. He's got a young/fit body that's super attractive (and will look amazing naked). While I do keep my self in really good shape, I still have the body of an almost 40 year old woman who has had 2 kids. I'm just so scared that when I get the courage to take off my clothes he'll look at my older body with all my stretch marks, get disappointed/turned off, and think 'I could do better than her. There are plenty of younger/hotter women who'd be with me'.

Additionally, my ex-husband (who is older than me) left me for a much younger woman. That's adding a lot to my fears and self concerns (especially since my boyfriend is younger)

With that being said, my boyfriend often expresses a high level of attraction and desire to be intimate with me. However, I just get scared that what he's thinking in his head isn't the same as what he'll see when we get intimate, and he'll get disappointed after he sees me (and maybe leave me for a younger woman)

How can I get over being so self conscious about my body, and not be worried about being intimate with my boyfriend?

Also, I feel kind of silly for feeling this way. I'm an established middle aged woman. Feeling insecure about my body and what my (much younger) boyfriend will think makes me feel like I'm being silly/ridiculous. However, it's where I am.
