Hilltopper,
My wife said the very same thing about sex. She said she was "sensitive to latex" (so no condoms) and she wanted me to get a vasectomy.

I refused a vasectomy. And I'm glad I did because I'm getting divorced now.

But I know an older man that got one years ago and he said sex went up 100% after he got his because hsi wife didnt worry about being pregnant anymore.
