My Wife Starves Me Of Sex

Help Help! I think I am going crazy and I really need your help. I'm 32 married to a 31year old for 6 years now with two kids (4 & 2).

Recently I figured out I'm having more sex with my wife every night and she's complaining a lot, though she isn't the sex or romantic type of woman but i thought i could teach her like everyone adviced me, it's embarrassing me. Everynight i have a strong Attention but no luck from my wife. I want someone who has overcome such experience to please tell me what to do. Be it drugs or social attitude.
