Sometimes cougars who look surprisingly younger than their actual age have super cute teenage boyfriends and it looks okay at some point yanno. Same goes for the men. But even though it's cute and might even be called love, I don't think those kind of relationships will even last long.
Like, yes it might look hot, beautiful and all but then I always think, 'blegh, magbe-break din naman yan sheesh!' and eventually they always do.
So all in all, for me age doesn't matter. What matters is how you stay together for long despite the age differences.
