i'm not sure what your seduction tricks are. but why don't you woo her like you did before y'all were married. the dinners, the flowers, the compliments, ect. make her feel beautiful, and wanted and appreciated. do anything to boost her ego. i know plenty of girls with low self esteem that have sucky love lives. make sure she understands that you still find her body insanely hawt. flirt with her, coerce her, do simple things she'll appreciate. house chores she might usually do, u take over once in while, errands, cooking, ect.
i know it seems like a lot of effort but it shouldn't be, if your not doing this already, u should be. trust me she's going to appreciate all the effort, and she'll do more of things you want because it'll make u happy.
Yeah those are the seduction tricks I know.
