Somehow this one struck me as female. Wider hips and thinner waist, more slender-looking. The lack of breasts makes sense, I doubt it's easy to suck on anything with those mouths (and I certainly would let them near mine). And a female being larger than a male is normal in like half of the species on Earth, so I'm kind of head-canonning this as female
Oh, I'm so glad you painted this one! I was wondering if I should get it or not but I wanted to wait for a painted version. It feels really feminine though... Is it a female but with small/no breasts??
