I'm trying to figure out if I might qualify as demisexual. I have never in my entire life looked at another person in real life and said "Hey, wow, I'd like to have sex with them" except my wife once we were together. Like I wasn't interested in the idea of sex with her until we were very close emotionally. I don't often look at people and find them attractive - as an adult I have worked out what other people call "attractive" and can recognize it but it doesn't make much of a difference in my opinion of someone. Seems like textbook demisexual except that I also really like porn and erotica. A lot. I create mental fantasies where I am with men and other women besides my wife, and I am aroused by those fantasies. From what I'm reading, demisexual people aren't usually aroused by porn. So maybe I'm just weird?
The thing about porn is that it doesn't usually relate to sexuality. I'm a lesbian that only likes straight and gay male porn, but the idea of being with men disgusts me. I think It's more about the scenery than anything. As far as demisexuality goes, It's pretty normal/common for most people to not want or think about sex until they're emotionally close to someone. Not everyone likes or wants casual sex or even thinks about strangers that way at all. This is especially common for women (and possibly just AFAB people in general, because of how slow the vagina is to react to sexual arousal and such).
Completely normal. Fantasies and sexual attraction (or lack thereof) don't necessarily mix. I'm also demisexual and I watch porn. I'm not attracted to the people on the video- it's more of the idea of them or what they're doing. If we were in the same room, nothing would happen. You hear about straight women that watch lesbian porn, but don't have any attraction towards women.
