I'd agree totally with Max - life includes sex and violence.
When I was 10 years old, I bought the Sex Pistols record "Something Else" My parents took it away from me because of the B Side Friggin in the Riggin
Hearing that as a ten year old has not caused me any lasting damage, and looking at it now it's a very dull lyric.
The vast majority of mudcatters doubtless have erotic encounters in the privacy of their own bedrooms, kitchen, gardens or wherever.
The idea of marking songs with a warning in case they offend anyone is absurd.
Folk songs are about life, and I for one am glad that life involves sex
