This was my first book of sexual humor or "humor sex book." I owned a copy of it in 1953 or 1954 -- 66 or 67 years ago, when I was only 14 or 15 years old. People didn't talk about "sex" back then. So "Over Sexteen" was the first book the public could read jokes about sex and be amazed about. The humor is pretty simple compared to today, but "Over Sexteen" is still fun a lot of fun to read. "Over Sexteen" is a classic!!! Buy it, read it, enjoy it, and try to stop smiling! Today it's rating would be PG-R, but definitely not X.
