The Chabad Hipster Hassid?

How common is this practice in the hassdic world?

I guess what's more important to ask is which rabbis and in which yeshiva's are young men being taught that "anal sex and that it was the perfect way to evade the virginity doctrine"?

I've heard to many stories of observant men sexually assaulting women in this same fashion. Does this making it halachially correct?

Please note, the article may be triggering to some survivors.
