It's intimidating, but so are tall males. Height in general is intimidating because we're designed to recognize that tall people produce a lot more physical power than short people. Not because they're automatically stronger, but the longer limbs create more leverage (distance from the point of rotation, etc) and put more brute force in the movements.
Some guys will be turned off because they're intimidated by you. Not every guy likes that. Just like some girls are intimidated by a very muscular and tall man, some guys are intimidated by tall-ish (say, 5'9") girls with Playboy-esque proportions, and some people in general are intimidated by others who dress with a lot of status symbols (rich clothes, drive a Mercedes-Benz, etc).
There are areas where you are not too tall and your height will give you a distinctiveness that other people will be drawn to. The modeling industry loves tall girls because they are intimidating in a sense. If you tall and walking down a runway and strutting your stuff, well there's a lot of inherent power to that and it gives lots of emphasis to whatever you're wearing. Or, you might find it easier for yourself to get a tall guy, being that the easiest way to obtain a desired trait in the other gender is to have a bit of it yourself.
So I mean, yea, maybe to some people, you are too tall. But everybody is too "something" to someone else. I am not in either extreme (short or tall) when it comes to height, I'm closer to the middle than you are, but that just means to some people I am too "boring" or "normal". And that means to someone else, I am just right. So yes, you're tall of course, but you're not too tall for the world.
I mean I know you're going to think about it again later, I can't tell you "don't worry" and you'll just stop. But the next time your height crosses your mind, just remember that it's not possible to be accepted by everybody (even if you were accepted by virtually everybody, there would be some people who dislike you because you're so popular that they think you're fake). And that in your case, a lot of the people who think you're too tall don't like you because you're undesirable, but because your height is so unique it's difficult to handle. And you have a gift that is very sought after by a lot of people.
So basically, I guess I just said, "no it's not too tall" ha
