While not the most physically compatible, a Zigzagoon's natural curiosity and desire to investigate everything leads them to be very open towards exploring many different sexual kinks and fantasies. Their incredibly common status, and belonging within the largest Egg Group, would also imply that they are very promiscuous and fertile in order to breed so many new members of their species. The only logical conclusion here is that Zigzagoon are natural-born sluts ready and willing to enjoy the many wonders of sex just for the fun of it.
And of course, once they evolve into Linoone, things are no different. They're still horny sons of bitches but now they're no longer experimental and have the focus to know what they want. Linoone have their fetishes and will be very straightforward about them.
They even come in two different flavours - the more friendly and supportive Hoennian variety versus the feisty and aggressive Galarian variety to best cater to your tastes, the latter of which can even become Obstagoon if you're looking for a more humanoid partner.
