I have the same issue. My husband and I waited until we were married to have sex and on our wedding night and for the most part ever since for the past two years, I don't feel anything. In my past I never had this issue. He is not a small guy by any means. Occasionally (once every 6 months I guess)it's like my sex drive and sensations will come back for one time only. That's how I found out that it's not him, it's me. I find that I get angry during sex because I can't feel anything and the whole thing is awekward because I'm not into it. So here's what I've found out may be the issue for many of us.
1. Have you ever been on birth control?
2. Have you ever taken antibiotics?
3. Do you eat an american diet (which is laden with processed foods, hormones, refined sugars, and pesticides)?
4. Do you get reocurring yeast infections but over the counter and prescribed creams don't really make it go away.
If yes to any or all of these then you may be suffering from an extreme case of Candida Albican. Search the web for the candida diet. This bacteria is resilient and is affecting many women in this country without them even knowing it. My whole 20s I've had issues with yeast infections. Three months before getting married I got on birth control again and I think that was the straw that broke the camels back sex wise. So educate yourself ladies. I hope this post helps.
