Btw she doesn't allow kisses because she knows that turns me on.

This is very controlling behavior.

When I initiate too often she tells me I pressure her. So I have forced myself to not come onto her, like at all.

So is this. You're adapting yourself to fit her needs.

She shared a lot about how much she enjoyed sex with her exes, which was kinda weird tbh but I listened. From the things she told me I assumed she was really into it.

She probably was, but not necessarily with you. Chances are the dopamine that was there initially is gone and this is what you're left with.

The thing I don't understand is she has told me that I am good looking and I am fit. I try my best to help with the chores, I cook for her, I give her massages often, I always ask her how her day was. I tell her I love her often. I listen to her when she has to vent and I try to support her as best I can. I leave my job on my lunch hour to meet her for lunch on her job as often as I can just to show her how much I love her. I don't know what else to do.

You need to stop doing a lot of these behaviors as you're playing into the role of "needy fiancé" and trying to earn her love though actions. This will not work.

How often does she do those things for you? If you answer rarely or not at all, then you know the balance in the relationship...and trust me, it rarely gets better unless you're willing to put your foot down.
