Alittle more than a cut?

I am new to the game and am looking over scenarios to see if they were situations where I should have made a move. Alittle while ago I was talking to a girl in one of my classes. Our conversations were going on for about two weeks or so. One particular day she had a scraped some skin right above her buttcheek. This cut occurred right before class, where it was just with me and a lesbian chick. The girl showed me the cut that was above her buttcheek. Was she perhaps showing me a cut or her butt? The cut was rather small and she asked me two times so she could know if it was big.

It really depends on other factors and body language she was giving you but yes she wouldn't show you her butt on accident

It may have been a legitimate question with the side effect of showing you her butt which she was totally aware of, or it coulda been a huge excuse to flirt with you
You shoulda tossed in a few lighthearted sexual jokes to judge her reaction
Like "ahh man it's really hard to tell you may need to take those all the way off"
