I've read quite a few YA books where the female protaganist cuts herself and the male protagonist doesn't hesitate to tear his shirt off to bind the wound. Talking with my husband I asked him, "If we were in the middle of nowhere and I cut my arm, what would you do?" He said he would tear a piece of his shirt off, a sleeve or the bottom, but not the whole thing.
So I think this is just a clever way to get the male love interest half-naked, but it's starting to become a little cliche, so how else can we get a guy's shirt off? What would you like to see? (Besides a little more fictional skin?)
Any other ideas? Post them in the comments. Whatever gets the most votes I'm using in my next manuscript.
