Sex in relation to Rock music has been taken to the extreme over decades anyway and for me it's a burden to explain to people in the audience that it isn't always that way. Many original Blues masters from the Mississippi delta and Chicago had been deprived of sex through the tragic environment of slavery. It may also have been out of desperation that they wrote such lyrics because of the times they were living in where upon sex was bad and disrespectful just as Ray Davies quote in "Victoria" that sex was bad and making reference to life in the pretense in England or complaining about the current lifestyle and rules of the British in THOSE times. Also take into account that a white man would not be judged for rape , but a black man would.All these tragic experiences seemed to be evident in the Blues. The stories of sex and the unfairness of it in the South or the desperation to have sex and a world of their own which no man ruled over.   Blues and Rock n' Roll ruled over these trials when it became appealing to a white audience. You wouldn't be discussing who you had sex with to a slave owner from the South unless you wanted to be abused or punished. Maybe not in all cases, but it certainly seemed that way to me. I assume if you protested against the rape of your girlfriend/backstreet girl/wife by a slave owner you would be executed and I've discovered Blues lyrics relating to that. Some of the sexy lyrics in Blues contain references to voodoo/mojo, witchcraft, and a desperate cry to be with a woman.  Words like "honey bee" and so on...were sexual. 

In the past...Prog has covered the areas of Gnosticism where it was not thought of as kindly measures to be feeling proud of an imperfect world and an imperfect body or flesh garment. Prog has also spoken of Satan in a ritualistic way. It has often made reference to having sex with demons or even Satan himself. Prog touches upon the subject of sexual intercourse through a religious or supernatural experience. Blues touch upon the same ideals , but was more "down to earth" with riddles and sexual references in the style of street talk.
