Experimenting with ones sexuality is an experiment. It's defined as such because going into the experiment they are generaly unsure of their sexuallity and the want to decide which hypothosis works best ie. homo or hetro. I assume that words mean what they mean because thats the only way to communicate here.
Yeah, but it's very unlikely that experimenting with your sexuality would make several of the girls spontaneously disappear. In fact, the 'nature' of the experiment is not risky at all. The only risk is that somebody's hiding in the trees with a video-camera...
While experimenting has the same technical meaning, its connotations can be very different.
Basically, you can't expect Mr. Sowah to use the logic 'Experiments are risky, for there's a billion-to-one chance that hammering this sword will cause the universe to implode, so I'd better think twice...', because that's ludicrous. Same with 7 pounds of metal disappearing.
