Something Random
Wobb is trying to be a boy. He's also not into the whole harem of various monsters bit. He just wants one person to devote himself to, and smooch all over!... He's young and innocent, don't break him right away.
It's a joke XD. Besides, trying to be a boy? Label it genderless, give it that hair, those thighs, and you have a recipe for a few confusion boners. You could fool me.
On the other hand, Suu is only like that because she took interest in a house full of PERVERTS. Every female in Monster Musume except for Suu is openly and clearly thirstier than every girl in Danmachi.
