I was raised in a religious home and didn't lose my virginity until the embarrassing age of I was told by the church to save it for marriage and I was a virgin until I met the woman who would become my wife at a party. I said to hell with it, we had a one-night stand, and we've been together now for eight years. I'm tall and slim and my wife is short and heavy. Like an idiot I believed it's what's on the inside that matters. My wife is the sweetest, most thoughtful person I've ever met and I love spending time with her, but I have absolutely no sexual attraction to her. As a result, I've all but stopped initiating sex and on the rare occasion when we do make love I make her come twice while I'm struggling just to get off.
