Maybe you've misdiagnosed the problem here. Maybe it's not that men are put off by your confidence but rather you may have a knack for offending people. While it's true that you shouldn't try to be someone you're not to please someone your interested in, sometimes you do need to change certain mannerisms in order for a relationship to work (eg, an easygoing but lazy guy may have to become more proactive, but he shouldn't have to act aggressive to please his significant other.)
On the other hand, it could just be that your going after the wrong guys, especially if you've drawn this conclusion from the results of one or two dates-gone-wrong. While you are correct that a lot of guys dislike a strong willed girl, I've heard enough opinions to suggest that just as many admire that trait in a woman. My guess is that less confidant guys feel intimidated by stronger willed girls, and confidence is not a trait typified by geeks. You see, your statement about guys liking strong women in video games doesn't really say much as, in a videogame, you interact with them through an idealized male protagonist (I'm sure the Grey Warden never has to deal with sweaty palms or acne).
Hope that helps.
