Pretty sure I mentioned it before in another like thread long ago but here it is once more.
WAIFU/ Rei Ayanami or Kos-Mos. My reasoning is simple. I feel either one would have little to no interest in sex and neither do I. On that note I suppose Aigis or some Persona 4 android chick would work but I feel I would get along better with Rei or Kos Mos.
If I ever did get my labido working again maybe Velvet (Odin Sphere), Angela (Seiken Densetsu 3) or Misturu (Persona 3)
And now for some new material... the HUSBANDO!!!
Well, since I'm a fairly girly-guy I want a REAL MAN to take care of me. While my fav male game characters are Yuri (Tales), Tatsuya (P2), Shadow (FF6) with Logy currently making some headway on the list, I like them all because they remind me of me in some sense. As for the HUSBANDO I think I would go with one of the following...
Barret (FF7), Rand (BoF2, since D took Garr), Akahiko (Persona 3), Garrek (Sp?) (Record of Lodoss), Cyan (FF6) or Goku (DBZ).
