Seriously just google "[insert species here] penis" and browse the images. Problem with resources like >>76880 is that they're only SORTA right. A lot of time they're not based on reality but based on artists referencing other artists. It's like that old game Telephone, where you whisper something to one person, who whispers it to another person, etc.; and then at the end of the line the message has been completely garbled. That's how you end up with artists drawing dog cocks upside down, or with the urethral opening in the wrong place, or thinking that lizards with hemipenes erect both of them at the same time, or whatever else. Don't be that artist; don't contribute to that mess, either. Draw from LIFE, not from someone else's mistakes.
Trust me, the FBI/CIA/NSA/BBQ does not give a flying fuck, and neither does your IP, and if you share your computer with someone who does care GET YOUR OWN FUCKING COMPUTER. In no country are pictures of animal dicks illegal.

99% of them are just dog dicks with some spikes or ridges on them.
