Brock, your quote is from 1974, but they still raved on about this through the 1980s. I was a teenager and heard it from the PLATFORM all the time. Small children were exposed to this stuff.
Maybe if you're in your early 30s or younger, it wasn't a big deal, possibly, but if you're nearing 40, then it was certainly a big deal made out of it in your formative years.
Just to clarify, what happens in your bedroom is your business and your business only. You do only what you're comfortable with. But to mold your thoughts on the subject by repeatedly pronouncing that oral sex is vile is a violation of your volition (alliteration, anyone?) on the subject.
