Of course, a lot of activities carry risk; doesn't mean teenagers will completely abstain from them.
The missing piece here might be that, as a teenager, it's pretty easy to convince yourself that the main way girls will reject you is by expressing that they're uncomfortable. (I believe this is called "getting the ick" in modern slang; the old movies your parents like call it "get lost, creep".) So if you're afraid of rejection, it's plausible that you'd be afraid of the legal consequences of making someone uncomfortable more than the personal embarrassment or emotional pain of the actual rejection.
