How to deal with being fresh on a coed team?

Going out for crew, been lifting but we run up a goddamn hill and down one to the boathouse which kills my legs, calves and shins. The males and females practice together and I can feel the judgment they're making. I'm by no means the tallest on the team and as a freshman I'm virtually invisible to freshmen girls.

Regardless of how I sound, I'm a) not going to quit and b)not autistic. I do lack natural social skills mostly because I try to conform to Carnegie and I don't just go fuck it and talk about whatever.

How should I handle this?
