The last thing you'd see when he walked away would be a stubby tail twitching happpily.

The first thing you'd see when he walked toward you would be a not so stubby always stiff 'tail' bobbing up and down happily as he danced along.

Always ready to make a young maiden smile or an old maid squeal, his pipes can soothe and arouse the hardest heart and calm the hottest rage to fan other flames instead.

He's about four feet tall, as furry as any man with his legs hairier than any goat, the stiff wand between them never hanging down for even a moment with a long goat shaped very full hairy sack swinging back and forth at every step.

That's as much of a description as anyone should need, he's a satyr and he looks like one. If in doubt, look at his portrait.
THAT saved three pages of typing.

He might wear a colourful vest or jacket but not much more.

I'm not a big fan of forcing 'extra powers and abilities' on people, but if you want to say his music has a captivating or arousing effect, I won't argue with it ;)
It doesn't have to and if your character falls under a spell of some sort then that's your choice (but it makes for fun RP)

He's a satyr and acts the part, any old place to put his dick is fine with him.
It's nothing huge compared to some but it looks large for his size and always seems to be more than ready to go.
He wouldn't lower himself to rape but any female of any sort that doesn't walk away or say no is giving him an invitation to pay a little closer attention and they'll definitely get some paid to them.

Fauns on the other hand, if they don't succumb to the music, will be run to ground and mercilessly and repeatedly ravaged almost to death, be warned.

Females preferred, there are Dryads around for others to use if they need to stick their dicks in something

But he can't resist a warm place to put his dick and those having both parts might just get a reacharound for their troubles, but they probably won't get it sucked.


Preferences:
He's born to breed and not much else, anything that looks like a vagina is fair game to him and he won't stop until it's been filled repeatedly.
