First of all, let’s just agree that porn would be a lot more interesting if people bumped uglies like slugs did. Let’s also agree that sex in general would be a lot more…umm, let’s say totally frickin’ devastating.
With afterglow, the less enviable aspect of slug sex can occur. Here’s one major drawback to being both large and adhesive: The sexual organs sometimes get stuck. In this case one slug gnaws off the other’s penis in a process called apophallation. (The dispossessed slug then goes on with life as a female.)
Here’s hoping female homosapiens don’t get wind of this clever trick — though if they do, I imagine Lorena Bobbitt will be the woman to lead them.
