Sex? Are you crazy?

Recently, I was approached by an attractive, flirtatious member of the opposite sex. The alarm bells went off in the head and I understood that I had a green light to proceed.

Unfortunately, the very thought of sex (and intimacy) with someone just turns my stomach. I'm not gay, but sheesh, I don't know if I can emotionally handle it.

What is wrong with me? It's been close to three years without intimacy and then when it's all teed up, I can't do it?

Yikes!
