But that sexual attraction develops through interaction, not just by seeing someone.
That's what a lot of people would describe as demisexuality - it's not abnormal, it's a normal variation, but likewise many many people do not need to have interaction to experience immediate sexual attraction. They just look at someone and completely unprompted their brain can go "wow, they are hot and I would like to do stuff with and too them".
If you would prefer a partner who experiences attraction in the same way as you, you are of course free to seek that out - there are many demisexual people out there who do not experience sexual attraction until they have formed a bond with someone.
But you cannot demand that other people police their attractions to fit the same way you experience them. You can only ask that they respect the relationship with their actions.
For example, if I see someone I find attractive, I find them immediately sexually attractive. From accross the room or through a movie screen - I don't need even a single interaction to have a sexual thought. I can choose whether I act on that or not, and given that I'm in a relationship I always choose not to. But that doesn't mean I don't have thoughts or fantasies that are entirely involuntary and it would be entirely unreasonable for my partner to expect me to police those thoughts and fantasies (although entirely reasonable for them to not want to HEAR about them).
