Losing my sex drive what can I do to get it back?

I am 28 years old and I am never in the mood for sex anymore. I remember a few years ago just feeling the feeling of being horny and wanting sex.

Now I could easily go months without thinking about it. This does cause problems in my marriage. He thinks I’m not attracted to him anymore because I’m never the one starting or asking him for sex. I love him and I miss the feeling of wanting sex and actually having a sex drive. I have even thought about buying a women sexual enhancement pill like pink pussycat pill. What can I do to get my sex drive back?
