I’m an older man, who for my entire life have only been with one woman. I’m now widowed nearly three years. Lately I was asked by a friend of my wife if I would be interested in being a f/ buddy. The first time we did it the woman was so disappointed. I’ve only ever made love to my wife and we were never adventurous. My wife never liked oral and it was always the missionary position. I’m so embarrassed that my lovemaking was so poor. I can’t really ask the same woman to help me become better. I’m actually thinking about not bothering with relationships as I’m so poor at the physical side of a relationship. Are there any books or videos that I can read or watch to gain more knowledge.
