Ahah are you a slut that only cares about appearance? 
Can't tell if you are serious or not, but as Otis said, as long as the person doesn't make me throw up. Their personality plays a major role though.
I also care about my own appearence simply for self perservation. I'll elaborate tomorrow if you wish.
Speaking of swimming, that's actually how I got my muscles, including my abs. I was swimming competitively for around 6 years, stopped 5 years ago when I moved to Canada. Haven't worked out a day in my life.
I'm kind of interested in gymnastics now, purely for fun though.
