Female serving in the Coast Guard?

I know that females can serve in the military if they want to. I've looked up almost everything I can about the Coast Guard and I'm determined to join when I turn 18. I'm fifteen right now. I know that I'll enlist, but I want to become a rescue swimmer. Yeah I know the training is hard and you have to stay fit. Thing is, I don't know if the people there are sexist. That may sound a bit pathetic, but if I have made it that far then I don't want guys dissing me because I'm a girl. I know that girls can't gain muscle as easy as men can, so it takes alot more to have the same strength. Yet as far as I know, men and women both have the same standards to be a SAR Swimmer. Would it be beyond my abilities to be a rescue swimmer or would I be better off choosing a different job in the CG?
