Christians does this count as pornography?

I want a Christian woman to marry. I have a navel fetish and I want to meet a girl who is ok with it. I'm not going to have sex until I'm married. However I want to do stuff like play with her hair and blow raspberries on her belly button. I'm trying to avoid looking at real navels when I see them in public because I want to avoid lust. I learned some time ago that different ways to blow raspberries on the belly include pressing the lips directly on the belly and blowing. When that time comes I will blow raspberries by sticking my tongue in between my lips and blowing like that. I googled the comparison of the two different ways to do it and I even pleasured myself to the ai descriptions. I've stopped doing that. Is it pornographic that I did that? I also want to blow raspberries on the belly of my future wife. However I'm not going to have sex until I'm married and I will not look at porn. When the time comes and I'm married I do want to keep stuff like my fetish a secret between me and my wife. No one outside our marriage will know about our sex life.
