Ignoring that factor, you are aware of the "gel" that a boar puts out, right? Many seem convinced that it only happens at the end of the breeding, but from what I've seen, it's *fairly* constantly produced as long as he's ejaculating. And the consistency of the gel produced by the half dozen or so boars I've handled sexually has been universally thick, sticky, and hard to get rid of - Almost like sticky bread dough.
