Because your brain has layers and the cognitive sequence doesn't begin in the frontal lobe. Your reptilian brain responds first with an instinctual feeling of either threat (fear) or non-threat (safety). Beyond that, it goes up into the limbic system, which is part of your mammalian brain. At this stage, the input gets translated into an instinctual emotion like hunger, sex, anger -- and we are talking really basic instinctual emotions that even dogs and cats feel at this point, nothing identifiable as "human" yet. Once it reaches the frontal lobe, your cerebral cortex, you use language and concepts and symbolic interaction to associate those emotions with ideas that you have formulated or acquired over your lifetime. Those emotions then get labeled and filtered and express in the complex ways that humans socialize with each other and construct their worldviews. They become FEELINGS at that point, ethics, values, moral instincts.

But remember, all of that is essentially rationalizing what began as a very crude very instinctual response, and evolved up into this higher strata of human behavior. And we only experience that higher level strata, not the sub-stratum of our cognition. So we are deceived into perceiving the thoughts as being what comes first, or the feelings as what comes first, when they're not. Plus there is neurochemistry to consider, half-lives of the neurotransmitters in your brain which need to break down before your mood can shift and you can calm down after an argument.

Really study neuroscience a bit to understand critical thinking and emotional intelligence. It helps to understand people a lot better.

Tl;DR, your million years old monkey brain sees pussy and wants to inseminate it, period. Ugly, voice, none of that matters. See pussy, fuck pussy. Then your humanity intervenes and tells you to breed SELECTIVELY, but that's a higher cognitive process which can be bypassed if you are horny enough and just want to FUCK.
