A difficult one for me. I would pick the first because that would be the one I'm attracted to. Sex is about a lot more than intercourse for me and I'm the one in control in any case so it's mostly my abilities that matter and not hers.
Now if the question was framed differently it could be different. I would rather be with someone that isn't the best looker than a girl who treat her body like it is made of glass. But she shouldn't be ugly as well.
