I don't think you understand how hypotheticals work and why they're useful.
This particular example is about a sex act that happened by accident. While falling down is a ridiculously improbable, similar instances are not. Once at a party in dark corridor I grabbed a woman who I thought was my girlfriend (whom, I confirmed previously, was liked being surprised in this way) but turned out it was someone else. I was mortified and ashamed, and had I been religious, this would have been exactly the example I would have reached for.
