Your gay
Go away, play mass effect if you want inter-species romance. Iconians are avian-like and do something similar to laying eggs. Kalakarg are close to squids, they lay eggs in water. Lacamptu are cloned, modified, and cybernetically grown. Every 1 in 200 Toraai are queens, and they are the only ones who birth. Isekut are mostly xenophobes who would cringe at the thought of laying with one of another species. Kanulom are similar to marsupials, and that's just plain weird. And don't even think of the Kresh you sick forget they killed billions of people. All of the other species are incompatible with humans.
