someone has read black adventures..

Well you can hardly blame him for acting like this. Plasma intentionally made him an extremely sheltered and awkward person who only interacted with abused pokemon just so he wouldn't accidentally figure out how awesome people are.

Is it really unexpected that he is being as coy as a freakin' elementary student about all this? Hell, does he even know what sex is? I can't really imagine Ghestis giving him 'the talk'. Well, maybe he would do it by sending one of those servants you see in the final castle up to the kid's room in something skimpy. Still, the point is-he does not have a healthy understanding of human relationships.
