I married later in life (almost 39), and went out with a fair number of women. (I'm not bragging; apparently girls would kiss me and discover I was still a frog, so they moved on.)

Trust me, past about age 25, everybody has something weird about them. (This means that the guys aren't perfect, either.)

While you don't have to be graphic about it, you can say you're on a restrictive diet. I've dealt with vegetarians, vegans, religious dieters, allergy sufferers, you name it.

The only ones who bothered me were those who could only eat food from very expensive restaurants.

Good luck!
