you are horny. simple as that. Most guys want the fuck the shit out of any hole that fits their dick. Don't do it. I am guessing girls are MUCH better...because...they are girls...and youa re thinking of a TREE....get it? T-R-E-E!
Whatever wistles your kettle. It's not illigal as long as you don't do it in public but you might not like the feeling of small and sharp wooden bits penetrating your penis flesh.
SUPERSTAHR!
