I don't get foot fetishes either. Me and my wife had a conversation about this today.

Me and my wife don't have safe sex. It has been a few years since we stopped using protection. For a long time she was on birth control becuase we didn't want kids. We decided to try and we did for a few years and didn't happen. We don't think we can have kids but we have never been tested. She has a lot of irregular periods and has had a couple miscarriages when she was with her ex. Probable from malnutrition. She went to the doctor a few months ago and everything was on with her.

To me sex feels better without a condom.
