The Hollow Knight wasn't a prudish creature, nor was it naive. It knew about sex, and it knew the parts the biological males, females, and those who were neither ought to have. It seemed to it that Lobco had something similar to an ovipore, and therefore it would make most biological sense to give itself something similar to an aedeagus.

However, it knew that this was not just about sense, biological or otherwise. Lobco felt things like this with a passion it couldn't conceive of, and not just because it had tried for so long not to feel or think. What she wanted might be very different to what 'made sense' to have.

As it had no preference, and no feelings of discomfort one way other the other, the Hollow Knight reluctantly lifted its hands off of her, and quickly signed.

"No. Shall I try different ones?"
