Kimmy, i do not agree on your usage of addressing them as 'freak'.
Other than earlier realisations, it is not surprising that some gay men discover their 'ACTUAL IDENTITY' later on in their life - ie. after marriage - and thus, they went on to explore their sexuality.
Of course, some of them such as my guy friend who knew earlier, married out of 'cover-up' or for some other reasons. I wouldn't understand the whole story behind it, nor would i name-call them based on my perspective.
