      The implicit assertion there is that it does no good for the individual to have a sexual relationship with itself and to better understand its own sexuality independent of dynamic interpersonal contexts. That hasn't exactly been ruled out.

      Yes that is an implicit assumption. But well founded. Our species doesn’t self fertilize.

      We also don't procreate with members of the same sex, yet sexuality manifests that way (and a wide variety of other ways). I think it's safe to say we haven't conclusively measured every facet of human sexual behavior enough for a predictive model of its evolutionary path.

      That’s absurd. Evolutionary puzzles exist. There is (legitimate and interesting) debate as to the causes of homosexuality. That in no way implies evolutionary insights don’t exist re sex (that’s *very* false). not that ain’t value to spotting the things needing evo explanation.

      Now you are suggesting that the causes for masturbation and homosexuality are causally unrelated. That doesn't seem like the simplest explanation, to me. I think we don't know what promotes and doesn't promote mutation in sexual behavior.

      At the moment, the most promising theory of causes of homosexuality suggests that the genetic factors that make eg men interested in men make their sisters so much more interested in men that the resulting reproductive success compensates for reduced fertility of their brothers.

      that seems plausible. Or that getting the dosing of sex hormones (and resulting neurochemostry) right is a complex error prone task. Or that creates help for other kin. Those r theories I have heard. Not expert/haven’t followed up on evidence. U? My $ is on complexity story.

      Both may be true. Homosexuality runs in families and male homosexuals tend to have more fertile mothers, aunts and sisters (suggests balancing selection hypothesis), and is more frequent in later births (complexity).

      Yeah. That all seems consistent with the complexity story, and just more likely when have some section for more of a certain sex hormone in lineage?

      The stats u mention above r well supported? (I haven’t looked at this lit since college. Recall it being messy then.)

      There is a bunch of papers on the balancing selection hypothesis, but I have no idea how representative they are for the field, or even how to account for the likely publication biases of research on human sexuality.
