My mom was pretty open with me and was pretty independent for her time. I think Dad liked that about her. Of course my grandma (maternal) never understood her. But the funniest thing about sex ed I remember is my grandmother asking the ladies (my mom, aunt, female first cousins and I) what oral sex was. When we explained it, she said it must be a mortal sin and she hoped none of us had done that! Of course everyone started looking at each other and giggling....Grandma was certainly perplexed at that!
