Am I really demisexual? should I be scared?

I (M21/straight man 100%} have had 4 crushes in my entire life. I live in Italy and most men would say I am lucky since it's full of beautiful ladies, but I just can't seem to have that initial spark with any of them. Yes I do love how SOME of them look, but to me it's all about compatibility. As a matter of fact, I've had three crushes in real life and one is a girl I met online 6 months ago that I loved so much. I kinda didn't like her at the very beginning but as I got to know her I completely fell in love with her. So yea, I don't know if this is normal or not. I'm very picky and have high standards, so maybe that's why. What I mean by picky is that I've never smoked and I don't want a gf that smokes, I want a girl that's fit like myself, someone who has the same interests as me (not all of them but a good percentage), shares the same values, morals, and standards, you name it.

With this last girl everything was perfect, but unfortunately she doesn't have romantic feelings for me. She sees me as an extraordinary friend. I'm still talking to her because she's a gem and don't want to lose her, but I know that if I wanna find someone I need to look elsewhere.

IMPORTANT: the main reason I think I'm this way is because of something an ex prisoner told me. he's actually the reason why I HATE p0rn with a passion. he told me that a woman's body should only be seen by her man. that stuck with me ever since and made me dislike p0rn. could that be the reason why I'm this way? dating apps disgust me too. I'm not in for sex. I want a real girl on my side. someone who's on the same wavelength as me.
