No, it's a lot more likely that the female sexual brain simply works differently from the male one.
There's also a mathematical paper (
https://arxiv.org/pdf/1703.04184.pdf) which ties this to the Darwinian variability hypothesis, making a probabilistic argument that the reason why women tend to be more 'average' than men is due to being more sexually selective.
The variability hypothesis has been empirically confirmed to hold for human populations, so there is no reason to think that there wouldn't be optimal selectiveness, which the sexual brain achieves through different desirability estimates.
