My stance on marriage vows runs deeper than that!
My parents were devout church goers, and I had to sing in the choir from age 6 until my 18th birthday, when I exercised my right as an independent human not to go any more, because I didn’t believe, despite 12 years of attempted brainwashing.
In that time I attended literally hundreds, if not thousands of weddings, and listened, really listened to what the priests said about marriage and the reasons for it.
One couple whose wedding I was in the choir for split up because the husband was a cross dresser. As it was a small village, and the pubs were more easy going in those days (my buddies and I started drinking in pubs aged 14 or so), I saw the guy regularly in the pub, and he was one of the nicest guys in the village.
His wife chucked him out, and he lived for a while in a tent on the village green, before becoming a drunken tramp (I think some unkind village kids set fire to the tent).
I couldn’t believe his wife had done that to him over clothing, especially when I knew that I had desires to cross dress too.
That certainly influenced me to keep it as big a secret as I could – and foolishly think I could just give it up.
