Loads of female aircrew in the RAF, and ssshhh, there are quite a few who show us blokes the way it should be done! I'd go as far as saying the vast majority of front line squadrons have female aircrew as a valuable part of their team, whether FJ, Rotary or Multis. Even the Harrier boys have had to accept theirs is not a unisex bastion any more! So go for it, the male/female thing will not hold you back in any way.
Oh, there is the fact that during training, there will be loads of fine young gentlemen around......but don't tell your boyfriend!
