Is it normal that i masturbated to naked pictures of myself?

Today my boyfriend and I were talking about me sending him nudes, and so I took a few and was contemplating sending them. About two hours later, I was masturbating to images on my phone and my pictures came up, and they actually made me incredibly horny and I had one of the best orgasms in a while.

You can't see my face in them, and I was thinking of my body as if it was someone else's. I was just thinking whether it's normal? Because the whole time I was aware that it was me, which is strange because I think that turned me on more..
