Evidence that in the eighteenth century Europe, men who had sex with the third sex (mollies) both were persecuted together without making a distinction between their identities, something which gave rise to the concept of 'homosexuality' which did not distinguish between men and third sex, nor between the penetrator and the penetrated.

"The Society organized the arrest and prosecution of Captain Rigby in 1698, which was the first time that anyone had actually laid plans and set a trap to capture a homosexual, and perhaps the first time that homosexuality itself, rather than sodomy in connection with rape or lack of consent or treason or other political motives, was the object of the prosecution. This trial prompted several satirical pamphlets, which brought homosexuals to wide public attention. The Society organized the rounding up of the first gang of mollies in Windsor in 1699, and a number of other prosecutions at the turn of the century. The Society publicly revealed homosexual meeting places in 1703."

Peer Pressure is the key to the process of heterosexualization

From what I'm observing now, Peer-pressure seems to play the most important role in forcing heterosexulaization on males who have not been heterosexualized till they turn 19 or 20.

Males who had almost come to terms with their sexuality for men and found male partners, with whom they were intensely attached have been known to break these bonds and force themselves to have relationships with girls, after going through peer-pressure.

Peer-pressure needs to be understood more intensely, how it works, who controls them, who are the people who lead peer-pressure, and all that.

And of course, how to tackle it.
