People who married your partner despite having an unsatisfactory sex life, how are you doing?

Look everything is near perfict bit n the bedroom. I have tried anything and everything to spice things up, it's as if she just drags on, not really trying from her side.ill take my time starting with a nice massage. Full body. It normally takes me about an hour then I'm done then I carry on but I make it more sexual and lots of 4play. Iv even asked her if I even excite her, are you sexual attracted to me, and she keeps telling me what I'd like to hear but not telling me the truth. Iv even nought awesome toys and the hole 9 yards. I now don't even mention it anymore, because she starts getting angry, so I can almost say I'm in a sex less marriage and it sucks

Anyone perhaps experiencing the same thing, maybe I can learn something from someone els, maybe om trying to hard, maybe I must wait for her to want to have sex, that actually might never happen then.
I do feel guilty seeking excitement els where, what am I to do, I do have needs, it's going for 10years now.

As long as she never finds out, she will never be heart broken, guess I'm wrong but that's the way I see it, I don't want to love another woman, I only want to enjoy some, not even sure I'll be able to do it once we get to that point, my guilt is strong.
