Someone told me today that the reason why Obito wants Infinite Tsukuyomi instead of resurrecting Rin is because at the bridge battle where he lost an eye, his peepee was also tucked onto that side of his pants, so not only did he lose one testicle (at least) he also lost his peepee, so he couldn't even stroke it to her anymore, therefore he only wants to live in a dream, where he still has his penis
