According to the most authoritative book - Bible:
"Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It is not rude, it does not seek for its own one, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres. Love never fails. But where there are prophecies, they will cease; where there are tongues, they will be stilled; where there is knowledge, it will pass away". (1 Corinthians 13:4-8)
And according to this quotation's (IMHO main) fifth verse ("it does not seek for its own one") - practical manifestation of it - heterosexual polyamory ( http://en.wikipedia.org/wiki/Polyamory ) including tantric group sex.
