Well, I can address the sexy jutsu. It's already been answered. There's a version that turns you into a man. Really, the exact one turns you into two men...making yaoi. And it works on the girls. o.o Sakura got a nosebleed.
Anyway, the point is, is, she may be a girl, but since Konohamaru developed a version that turns you into a guy, she can use that one and still have it be effective. Even if it hadn't already existed, fivetail would've made it up and went with it...and I, at least, would've let her.
And, I do hope I answered your questions well in that PM, Rika. I have a habit of either elaborating too much, not enough, or just plain not making sense to keep myself from elaborating too much.
I have a couple more jutsu to pick out for the leader character before I post him. Next couple of posts, promise! ^^;;
