Summary:
So, if we look at modern heterosexual sex, it is mostly recreational, it, too, is equally unnatural as homosexual sex. While there seems to be some logic in looking at homosexuality as unnatural from body physiology perspective, the reality is completely different. Sex needs hardware in the form of a reciprocating body physiology of highly-specialised sexual organs that execute the commands issued by the software of sex. Consensual sex between adults can't be in the purview of the state and hence Section 377 needs to be decriminalised when sex is voluntary. Truth is, sex in humans has transformed and gone far beyond its 'natural' purpose of procreation, and hence it can no longer be measured on the count of body physiology..
