/vp/, what do you think are the actual moral issues in regards to having sex with Pokemon?

(I could spend a few paragraphs trying to convince you all that I'm not into fucking Pokemon, but I know no one would believe me anyway so I won't bother.)

I'm not talking about whether you personally are sexually attracted to a Gardevoir. I'm just talking about the moral implications. Is it bestiality? Would it be illegal, like fucking a dog is (in MOST places)? Pokemon are, after all, sentient. And through sentience, wouldn't they be able to give consent? And thus isn't that MORALLY okay? If you lived in the Pokemon world and your best friend had a Gardevoir, and you found out that the two of them were having a sexual relationship and the Gardevoir *clearly* wasn't being forced and reciprocated back, would you care? Would you report him, suggesting that was illegal?
