I need help guys..I normally don't ask for advice because I don't want to be judged but yeah..please be nice.

So I've been married for almost two years and out sex life is just getting worse and worse it's seems like..and I'm kind of a bad flirt sometimes when I'm not sexually active, but I don't go beyond flirting and my husband knows about it, it's just how I've always been since we met. Idk what to do to spice it up or get it going again or whatever, it just sucks :/
