How to not overthink and be insecure about my (21F) "boyfriend" (24M) and his occupation.

I'll get out of the way about why I wrote boyfriend in quotations, and why I'm overthinking.

Long story short, he does sex work. Which isn't bad; I don't judge him for it, and he's actually a really sweet person that I love being around. We met at a party for one of my friends' friends, and to be honest, I had no clue who this guy was. I'm not someone who watches a lot, and when I do, I'm not really remembering names or faces. He was pretty open about it. We're basically dating now, but nothing's really been confirmed. He mentioned in passing that it was because he didn't want to feel like he was cheating, but he does still really like me. He's told me he loves me. So, keeping it "casual" would fulfil both those wishes. He would get to love me without feeling guilty.

Now I'm overthinking for two reasons. The first is because when I did, out of curiosity, look for a video, almost all of them featured women who resemble NOTHING of me. Whatever you're thinking of when you see a girl in the industry, think the opposite of all of that. In. Every. Way. I'm a woman of colour, of average height, thin side. So, think, a short blonde woman with exaggerated curves. All the videos were (obviously duh) sexual in nature, but sometimes he'd, like, say things (sorry I'm getting awkward typing this) within the videos about these women that made me go like...what is he with me for?

The second reason is that I'm also just not as experienced. I've done everything except the actual penetrative part of sex. I'm kind of just a naturally awkward girl to be around, so I haven't had many chances to catch up to the rest of the world. On the brighter side him and I have a lower libido (he does "get it" from these other women, but to be fair to him, he's not exactly filming every day, and outside of that I'd say he's on the lower side). We can usually just hang out romantically without expecting sex to keep us together all the time.

The other day I was hanging out with him and admitted I'd seen some of the videos just out of curiosity. He asked how they were, and I told him that I don't know what he sees in me. I'm not the type of girl he seems to enjoy so much, and I would probably not be as good in bed. He told me he enjoys me because I don't feel like work. It made me feel better, actually, but I'm just not sure how to stop feeling like I'm lacking something, or that he's missing something.
