Ya know, I wouldn't ignore the behavior from the teenage boys. Those teenage boys become men... eventually... one would hope.... if that attitude isn't corrected now, then when does it get corrected?
What I am going to tell you, you are going to tell me is really easy for me to say, but it did work with someone I know consider a very good friend. When someone says something to you that is hurtful, or meanspirited, or in anyway degrades you as a person and as a woman, challenge them on it. don't be a bitch about it and get in their face, but don't ignore it either. Ask them to explain themselves and what they meant by that statement. You will probably find taht tehy stammer and stumble over their words and really won't be able to give you an explaination. They do stop eventually.
But the point is, you don't need to tolerate being made to feel inferior for your gender, ignoring the problem doesn't make it go away, it only makes it worse. I'm sure the other ladies in your family would also appreciate your stance.

...
I am woman, hear me roar
In numbers too big to ignore
And I know too much to go back an' pretend
'cause I've heard it all before
And I've been down there on the floor
No one's ever gonna keep me down again
Oh yes I am wise
But it's wisdom born of pain
Yes, I've paid the price
But look how much I gained
If I have to, I can do anything
I am strong
I am invincible
I am woman
You can bend but never break me
'cause it only serves to make me
More determined to achieve my final goal
And I come back even stronger
Not a novice any longer
'cause you've deepened the conviction in my soul
I am woman watch me grow
See me standing toe to toe
As I spread my lovin' arms across the land
But I'm still an embryo
With a long long way to go
Until I make my brother understand
Oh yes I am wise
But it's wisdom born of pain
Yes, I've paid the price
But look how much I gained
If I have to I can face anything
I am strong
I am invincible
I am woman
Oh, I am woman
I am invincible
I am strong
