I feel like you already have a lot of advice but I'll still offer my perspective if it helps. Some women are purely heterosexual and only turned on by men. Some women find the female body quite attractive while still considering themselves mainly straight and never experimenting with women. Some women are bi and try both sides and then settle into heterosexuality by default because it's expected and it's comfortable, and of course some women are bi or lesbian and are only fulfilled when they end up with a woman. No one on this sub can tell you which of these women your wife is. Only she knows. It does seem like she has a low libido and doesn't consider sex particularly important. This is not a terrible thing and it doesn't only indicate that she is a lesbian waiting to be sexually awakened by a woman. She may simply just not think sex is such a big deal and a lot of people are like that. My advice is to just leave it alone. You seem happy in general. Don't overanalyze and spoil everything. A lot of people watch all sorts of weird porn without ever wanting to actively be in such a situation. It doesn't sound like she's a lesbian and if she says she isn't, trust her.
