Krishna's 'first night' with child-bride Rukmini

Spoiler: She 'fainted' after intercourse

Did Krishna have only 'spiritual love' with Gopis or also physical sex? Brahma-vaivarta purana explains Krishna's expertise in rasa leela:

Krishna had orgies at various places including a crematorium! Astonished by the sight, goddesses took birth as humans to have sex w/ Krishna

Krishna's son Sambha abducted Duryodhana's unwilling daughter Lakshmanaa from her Swayamvara. He was captured but Balarama negotiated peace.

Bhaktivedanta Prabhupada comments on Srimad Bhagavatam 4.25.42

A girl should be married off BEFORE she attains puberty & has sexual desires

A poor father laments that his daughter has exceeded 10 years age, exceeded marriageable age

Srimad Devi Bhagavatam
http://www.sacred-texts.com/hin/db/bk03ch27.htm

Vivekananda: "Just read the Grihya-Sutras.. it's expressly stated that a girl must be married b4 attaining puberty"

What was Rukmini's age when Krishna married her?

Skanda Mahapurana: She was Eight-years-old
Srimad-Bhagavata Purana: Her breasts were just "budding"
Brahma-vaivarta Mahapurana: She just attained puberty on the day Krishna had sex with her some time after the marriage.

Interestingly, Srimad Bhagavtam, the primary text of the Vaishnava sect of Krishna worship, NOT ONCE mentions the name "RADHA" as a person. The Brahmavaivarta Mahapuranam composed about the same period is full of Krishna-Radha rasa leela though. https://twitter.com/AnaMyID/status/927481345902764034

Krishna & Rukmini had 10 kids. First son Pardyumna married his uncle Rukmi's daughter. Rukmini's grandson(Pradyumna's son) Aniruddha married Rukmi's granddaughter; during post-marriage festivities Rukmi hosted a gambling game, Balarama murdered Rukmi cos he thought he was cheated

Hindu right wing site IndiaFacts quotes "The Wisdom of Puranas", specifically The Brahma Vaivarta Purana:

"Cow sacrifices were Dharmic in ancient India but not recommended in Kali Yuga"

From "A Case for Cow-Protection without Whitewashing the Past" http://indiafacts.org/case-cow-protection-without-whitewashing-past/

For the occasion of Rukmini's marriage, Rukmi tells his father to invite guests, and SLAUGHTER COWS, sacrifice animals, COOK PLENTY OF MEAT... and as an afterthought he adds "also cook vegetables".

Rukmini sat on her father's lap when she was given away in marriage to Krishna—Brahma Vaivarta Purana Krishna Janma Kanda

In present day India, this practice is still followed by some Brahmins, earlier child brides..but now an adult is made to sit on father's lap during marriage

Lord Krishna's eldest & most celebrated son Pradyumna (Rukmini's first child) was abducted as a baby by a rakshasa named Sambara. Sambara's wife Mayavati who never had kids raised him. When he grew up Pradyumna killed Sambara & married Mayavati, a woman older than his own mother.

Krishna's adolescent son Pradyumna was touched inappropriately by an older woman named Mayavati who practically raised him. He says: "Why do you indulge in feelings so unbecoming of a mother?". He later marries her.
