My rules about Romance (Putting it now instead of later): 
[b][i][u]DIVITIANS GO INTO HEAT LIKE ANIMALS[/u][/i][/b]
Except for Dragons and Avians. Meaning, you’re likely not going to try to have sexual relations with anyone, and it’s to your best interest to not go into heat.
Regarding Erotica: Keep it in a private chat, I know for a fact there are minors on this website, and I don’t want then exposed to this here. Drop subtle hints in IC, but keep it SFW. Also, no subspecies have breasts, except for the Dragon subspecies.

Subspecies Personality and basic physical Traits.

Aardvark: Typically keep to themselves, sometimes walk on all fours, eat a lot, have the nose, polite, 5’2”-5’6” and live to be around 60 human years old. Coloration can vary due to natural tendencies as well as dying.

Avian: Typically more resistant to mental stress, and are more agile than most others. This mental resistance often results in them being cold, stubborn, or overconfident in their abilities. They can’t fly, and are covered in more down than actual feathers, as well as have the typical bird hollow bones. They are oddly resistant to the effects of “Warp Cloak” and are typically the only race in major assassin guilds. (No, you cannot be part of one.) Normally live to be about 40 human years old. They have a beak that ranges from 4”-7”, and can be colored like any bird on Earth. Normally between 5’7”-6’4”. Are the only other race to not have a “Heat”.

Centipede: Typically more intelligent, and have twelve legs. Depending on the individual, they walk on either six legs or eight. They’re not very resistant to emotional or mental stress, but are very skilled at math and science. They’re normally 7-8’ long, and sometimes have an artificial Chitin if their original one rots or gets too small. Live to be around 120 human years old.

Crocodile: Typically not as intelligent as other subspecies, but make up for this in brawn. Their scales are typically augmented with armor, and serve as better protection than their Earthren counterparts. They stand around 6’7” and are the second tallest Divitian subspecies. Their mouths have not grown any weaker either. Live to be 55 human years old.

Dragon: Typically confident and charismatic, the Dragon subspecies basically runs the political structure of Divitia. They have enough wit to convince the less intelligent subspecies, and enough grace (And in the guys’ case, Swagger) to woo over the smarter subspecies. They’re one of the few Divitian subspecies that do not go into heat when they need to mate. About 70% of the Dragon Subspecies actually have wings, the other 30% don’t, but are a little bit taller. These wings are mostly used for show, but could potentially allow the user to glide short distances when not heavily armored. Their scales can be any color. Typically 2’11”-3’2” if they have wings, and 3’7”-4’2” without. They are the shortest subspecies. Live to be 300 human years old.

Lizard: This Subspecies has the most random of personalities, and range in similarities to Chameleons to Komodo Dragons. Their personalities are always extremely strong. For example, if they'd normally be someone who likes to keep in shape, they'd take it to the extreme of working out three hours a day every day. They are always taller than Dragon Subspecies, and shorter than Crocodiles. Live to be 60-100 human years old.

Porcupine: This subspecies are typically wimpier than the others, shying away from fights and other such things. Which is a tad odd, as they are normally muscular (Less so than the Crocodiles.), and do in fact have quills. These Quills range in length from 2’ long to 6”, and are fairly tough to break. They stand at above 7 feet, but are never tall than eight feet. Live to be 150 human years old.

Wolf: Typically peppy, cheery, and energetic. They very closely resemble their Earthren brethren, the only physical difference being they stand upright and can speak. They normally stand around 5’2” tall, and have an odd dislike for clothes. They normally act childish as well. They live to be twenty human years old.
