This is called "prison gay" and "prison sissy." In high-stress environments, stronger, more dominant males will sodomize weaker ones, who will then emulate typical female behavior. Common in prisons and also observed in many mammals.
Sexual orientation and behavior are mostly a product of intrauterine hormonal development and environmental hormones.
The reason there are more homosexuals today than in the historical record is because of endocrine disruptors in the environment, altering estrogen and progesterone levels of pregnant women. Conversely, the increase in rates of male bisexuality (which is now estimated at 40% of young men!) is due to increases in cortisol levels and the breakdown of offline social networks, which is making society more similar to prisons.
