I’m going to be careful with how I answer this question. According to the D&D 3.5 ruleset, a Kobold reaches full maturity at 8 years old and is considered an adult at 10. Xiik is fully matured and well into adulthood.

As for a partner, Kobold society doesn’t believe in monogamous relationships. Everything is communal, even child rearing, so there’s no one male that Xiik comes back to. Her role as Shaman also means she travels quite a bit and acts as an ambassador to other races and communities so she’s rarely around the same people for very long.
