No, not venerial disease day, sillies! (Or at least I hope not...)
I hope you're snuggling up with a loved one right now, gettin' freaky, but if you're not, you can always snuggle up with yourself, and perhaps a bottle or two of red wine. Hell, I have someone to snuggle with and I still might invite the red wine to the party. Go nuts! Have fun!
But just don't do anything I wouldn't do ;).
Happy Valentine's Day!
