Anyone else not interested in sex?

Been married 2 years now..and rarely have interest in having sex with my husband. Is this normal? Is something wrong with me ? And no..I dont need to talk to a doctor about this. My sex drive was always driven by new flings or relationships. The excitement and emotional intense interest is what always got me into it in the past..and now I just do it with him if I know it will be a quicky.

Any advice or similar situations?
