Welcome to another Texan! I agree that a male, female would be an easier combination to live around in most cases. Two little terrier males can really flex up on each other at times if they are both alpha or dominant-leaning and boy, as first dogs, it can be a trial.
Yorkies are quite frail unless you get larger-sized ones so be kind of prepared to turn into a watchful, cautious dog owner. They are head-strong, don't know they are subject to gravity, often prey-driven little risk-takers, despite their tiny size so know this going in. I hadn't had my Tibbe but 3 months when he jumped clean out of my arms as I was coming in the front door with him! He will go after any animal to chase it with purpose in his eyes! My little 3 lb. Jilly once got herself attacked by a 65 lb. Dalmatian by growling and lunging for it as it ran toward us. She had surgery and lived but these little guys are often reckless and headstrong so be prepared to be a strong leader and train, train, train once you get your dog(s). Healthcare expenses can be large. Still and all, there is no other breed quite like them and they are the only dog for me. Might be wisest to get one, raise it past puppyhood and then get the second unless you are extremely brave and love a lot of work. haha.
Best luck to you and your new dog(s).
