A person is not born gay! Homosexuality is an adaptation, not an inborn trait. It is not 'normal. On the contrary, it deviates (note the term-as in a sexual deviate) from the norm. Nature exists whether academics like it or not. And in nature, procreation is the single relentless rule.
Quit believing the myths the pro gay establishment wants you to believe.
The purpose of sex is to reproduce, the purpose of the pleasure involved is to bond, the purpose of the bond is to create a mutual co-existance between the man and woman so that their children are given good nurturing- nurturing required by both parents of both genders.
Homosexual sex does not equal reproduction. Homosexual bonds do not create a mutual co-existance as each gender has its inherent duties.
Is it really that hard to figure out?
