cohabing?

seen very mixed information on this. saw a post saying it was fine to cohab a male/female pair as long as you take the female out during breeding season (wondering how they can tell without being brumated like most reptiles...) others saying a male will harass/breed a female to death no matter what

also wondering if anyones experimented with cohabing with other species other than cuc? like a large harmless insect or diurnal micro geckos
