JefGoelz nailed it.
I guess the guys give you the chinese age old advice, with their rhino horn and tiger claw powders...
But let's remember that in Korea (and china too? Can't remember) DOG's d**k is an actual delicacy that is supposed to cure erectile problems and is served in restaurants.
So why not go out of the way and make it a bit gross, or fun instead of plain normal with the raptor's claw?
In France we get penis jokes sorted pretty early, and we had many disturbing ones, like guys going to lie down in a field waiting for someone to come and "harvest" (well, that was a "elongate your tool" joke actually).
My point is that you could see what the jokes on the topic are, they'd probably be full of good ideas.
