Lewd, Kilroy's genitals mention
Got penis on the brain today. (What else is new? Err, I mean...) Specifically, Kilroy's penis, and what it should look like. Because I'm sure you're all curious to know all about firelizard dick :P
Being of a species that mates in the air, a few things need to be considered. The design has to allow for fairly easy flying. So no 20ft horse cock that weighs more than twice Kilroy's weight :P A conical style dick would be sufficient. Fairly aerodynamic!

Another issue to consider is the whole 'getting it in while airborne' issue. It's a hell of a lot of precision and not a lot of margin for error. One wrong move and that's a bent dick or a jabbed thigh and that's no fun for anyone! More time wasted entering, less time for mating! A prehensile penis would solve these issues well. Get in position, and the dick does the rest! Also allows him to do silly things like carry around small items with his dick.

Then there's the matter of what to do to prevent accidentally popping out when ejaculating. There's nothing more embarrassing than winning a mating flight only to spill your seed all over the ground and disappoint your mate. Luckily, he's got a solution for that! The glans contains four small barbs extending inward towards his crotch, with a flap of skin all around connecting them like an umbrella.

Upon ejaculation it'll flare open and keep his penis lodged inside his mate for the few seconds it takes to ejaculate, then retract. Because of the dangers of a mating flight it doesn't take long for him to reach ejaculation, and even then it's only a few short spurts before it's done. Whie normally disappointing, this ensures the two can separate safely to prevent a disastrous end to a flight.
