I have been divorced for a year and am in my late 50s. After about 6 months of separation I began seeing a woman I worked with for several years. She was over 20 years younger than me. It was very exciting for both of us. Very passionate. We were careful to take precautions so she wouldn't get pregnant. We're currently not seeing each other and I don't know if we ever will, but hopefully I'll begin dating other women. While dating an older woman is fine, I could potentially find myself sexually involved with a woman still able to get pregnant. I definitely wouldn't want that to happen. My question is should I get a vasectomy on the chance that I may become involved with someone able to have children or even my former girlfriend? Would I be having unnecessary surgery? Would possible risks make it worth doing?
