Red river valley (the words) was written by an Irishman from Strabane called Jimmy Kennedy using an existing melody.
The melody is much older and probably originates from New orleans (at least George Lewis played it in the late 1800s) - this is not to say however that it may have been imported from Europe even earlier.
Personally, I love everything that comes from a pussy! I once was with a couple fooling around when she was on her monthly...her husband shot his load in her snatch, and I delighted in licking her clean, followed by her peeing and discharging her husband's load along with her menstruation in my mouth and down my throat!
Well I suppose it beat a shower, tampon, and going to the potty to piss...
Gumby, when I'm in the States and need a shit, and my crabs and thrush discharge are bothering me, I'll save myself a few coins for the public john and call you...
