One thing that doesn't "exist" in Singapore is seeing older gay couples. I never thought about it but here in Amsterdam you see them all the time. At the movies Saturday at least 3 couples in their 50's and 60's, and today in the supermarket another couple in their 60's.
Is it because the older gays in Singapore decided to get married to a woman? Remain single? Don't want to be seen in public as a couple? Probably a combination of all three reasons.
