This is the argument by some who oppose same sex marriages. Logically then all marriages should be dissolved when the partners become too old to bear children and proof of fertility should be a prerequisite to marriage. I guess these are the same people who believe that anal sex is a sin and fellatio and cunnilingus should be prosecuted as abhorrent behavior. I imagine these are pretty unhappy people who are afraid of their own desires.
I actually have some homophobia. It’s just not in my DNA to consider sex with another man. It has no appeal to me. But get over it! Not everyone is built the same. What you find exciting might not be the same as it is for me but why should I care and get my panties in a bunch over it. Live and let live. That’s the basis of freedom. It’s supposed to be for all.
