Frustrated

I'm in the bath working on my 3rd glass of wine, buzzed and horny. The only way to enjoy sex is intoxicated. I hate it. Been with my husband for 4 1/2 years. First 2 years were great. Now sex sucks. I havent had an orgasm in over 2 years. We have a daughter who is 14 months. They only reason why I got pregnant was I was drunk on 2 bottles of wine.
