...you watch "Two and a half men" on tv, see the Jon Cryer character get a blowjob from his girlfriend, and reflect on a time when not only were such things not shown on tv, but giving or getting a blowjob was a felony in 49 states and the District of Columbia.
Just a note: I am too old to be a "Baby Boomer"; I suspect a few others of us here are, as well. When names were picked, those of us born during the Great Depression up to the end of World War Two were tentatively called the "Skinny Generation" because there were so few of us. Our parents were the Greatest Generation, and they did a lot. What did we do? Well, among other things, we made oral sex both legal and "normal". Nobody's written a book about THAT, dammit!
