Based on promise keeping and duties - two fundamentals of Kantianethics
Kant says sex for duty or sex for lust are both disrespectful so that must be given by free given sexual acts that are mutually consenting and equal to give the dignity deserved to put us above animals
Marriage is not for sex alone but for companionship
Why is cohabitation a problem for Kant?
lacks commitment
danger the couple are using each other as a means to an end
Why is premarital sex unsupportable?
relationship not equal or based on mutual respect as it is based on lust and uses people as means to end
