Is that not normal?

I read a "better sex" book from the 70s and they recommended putting on candles. So I guess it wasn't normal back then. All the drawings had lots of hair, too.

Was it "The Joy of Sex"? I remember when I was about 11 or 12, I found an old copy that a family friend owned when they had a yard sale one weekend. My mum snatched it out of my hand so fast. As if that would do anything to discourage my interest.💀
