You do realize that producing a hyper realistic android is going to cost a fortune, right? Which means you as a potential buyer needs to start saving up lol.
Also, you want a girl that doesn't use the bathroom? WTF. GIRLS ARE HUMANS TOO DAMMIT
I suppose there's nothing less romantic that coming into the bathroom and smelling your partners... well, that's why me and my boyfriend will get separate bathrooms when we buy a house together in the future. Some people might call it stupid, I call it keeping the romance alive. Nothing wrong with that!
