popa_bar_abba: Is this from the Torah?

The meforshim on Nedarim 51a explain toeiva is an unnatural perversion of the human drive.

Igros Moshe (Y.D. 3:115): Toeiva is one of the greatest abominations that even the nations of the world know that it is an incomparable abomination. Therefore there is no need for any rationale to explain why it is an abomination that the whole world despises. The world already holds that the transgressors of this sin are disgusting and are not members of civilization at all. So when a reason is sought for this prohibition, this removes the obscenity from it. It removes the embarrassment, shame and disgrace and completely downplays the seriousness of this issue.
