@Tinkerbell2614: Why thank you! To quote Frank Zappa: "Without deviation from the norm, progress is not possible."
The weird people are the ones that make a difference and can change society for the better.
To give a better explanation of why we do it: There are unique pheromones in skunk scent that stand out especially on an actual full spray. Female skunks have particularly sweet pheromones, I've noticed, they smell like a combination of vanilla, bananas and marigolds and are very addicting and intoxicating to smell, so personally I prefer to be squirted by them. Males are mostly all stinky thiols but even they have some pretty nice pheromones to them. I find the scent not only quite enticing to my libido but also amazingly relaxing. When I'm skunked, I get in this wonderful relaxed, contented head space where all is right with the world and nothing can hurt me.
There's a variety of reasons people become skunkseekers though. Perhaps they simply love skunks that much and want to get engulfed in the scent as sort of a bonding or marking ritual. Maybe they have a stink fetish and want to smell as awful as possible without getting dirty or at least risking getting dirty and/or diseased. Or like me, they can detect the pheromones and just enjoy the scent immensely. I've even known someone that said they just like the funny reactions they get when other people smell skunk on them.
I don't judge and hope most people that look into this kind of thing won't judge either.
