I am probably the last virgin bride in the history of my family. And I grew up in a very protected and rigid Catholic family, so I really didn't know very much about sex in general, and the opposite sex in particular.
When I was a sophomore in college, one night after "lights out" we all gathered in one girl's room to talk about sex. One of the girls said she'd actually seen a naked man, and described his parts in great detail.
THe first time I ever saw an adult naked male was on my wedding night. And I was astounded. I asked my husband why his penis didn't have "concentring rings of hair." He looked at me and laughed and laughed and wanted to know where in the world I picked up that strange notion. I told him about the night in the dorm and said "Mary Francis (not her real name) said that's what men looked like." For several years I thought that there was something wrong with my husband because he didn't look like the dorm-room conversation had led me to expect.
