She wants me to photograph her in sexy clothes/underwear, is this normal?

So I (20 yr) have been together with my girlfriend (18 yr) for about a month, we’ve known each other for 2 months, we both got attention deficit hyperactivity disorder and we don’t hide who we truly are to ourselves, we dare oppose society and we are truly ourselves and conversate in full honesty... We talked about what we like and what turns us on and makes us feel validated. She mentioned she would want to take sexy photoshoots in front of my car and other locations in sexy clothing and just pose like a model and have me photograph her. This whole idea turns me on so badly because I love body expression when it’s private between the two of us, but I also feel like that something like this would be a bit odd, because I don’t see her sexually in a way that I only want her for sex or admire her body only, of course I love her that way, but I love her the way she is (personality and traits), and I’m not gonna lie... She’s my first girlfriend, I have insecurities and the whole idea seems very sexy to me, but I’m no erotic photographer, I’m afraid of the responsibility I need to take. I know photos, seen tons of friends had their nudes/erotic private photos leaked. I’m really not one of those guys, this is something I’d take to my grave, despite a rough break-up scenario. I’m just scared of her ever doubting my responsibility.

I’d also mention I have the leadership role in the relationship, I make all the plans and takes the initiative in almost all situations. She’s very submissive and has had a lot going on in her past, bad experience with guys if that explains anything.

I’m just so afraid of accidentally taking advantage of her because of her being so submissive. And I don’t know if her past has influenced this behavior in any way. What should I do to make her trust me in this situation? Because I’m not a f*ckup, I respect her to the core. Advice would be mighty helpful for sure. Is this behavior normal?
