>sexual arousal was only designed for male brains because they are the ones that have to go out and pursue sexual partners
Women exert selection pressure, not always, and there are confounding factors, but to a sufficient degree as to be very evolutionary significant. And even in cases of women being forced to sleep with particular partners, it is a survival advantage to, in so far as possible, seem into it to ingratiate yourself towards the kind of man who could get their way in a social structure and therefore would be likely to be in a position to decide you're their wife. Hence they need a completely alternate software for both selecting positive genes when they have freedom of choice, and happening to want the guy they would probably otherwise have to go with anyway, making him actually like her so she's less likely to be killed, or disliked beyond the immediate level of sexual attraction and afforded lower status and treatment which has implications for her offsprings survival and ability to in turn procreate.
The way the brain evolves workable heuristics that lend themselves to navigating these kinds of scenarios is in very large part with sexual attraction. They had every reason to evolve an alternate sexuality.
