After a little flirtin' with Death, I got to thinkin': wow, Tech's got a lot of noncanonical ladyfriends! Well... noncanonical yet/as far as you guys know. ;> Thought I'd give them all a little love with some in-character interactions from Tech.
Tech loves ladies. As friends, lovers, mentors, students, bros, soul-mates, you-name-it. He doesn't have anything against dudes; it tends to be a natural attraction, but man, ladies are so interesting. He loves listening to ladies talk from their point of view--partly because it's such a different experience from his own, being a fairly traditionally masculine guy. Tech might be a bit of a grump sometimes, but he's much more interested in others than his demeanor would imply.
Anyway, all of these ladies are lovely, and you should totally watch them. Also Rusty Nail, who is not a lady, but is lovely as well!
