Where did my orgasam go !!!

Help!!

Over the past month my orgasams have gotten weaker and weaker until now I can't really feel them anymore. If I Can get myself stimulated at all, building myself up still feels the same But then when I feel I am about to orgasam- I feel nothing! It's so frustrating and I don't know what to do! Had my thyroid checked and it appears normal. I am waiting for test results from my obgyn to see if I have something hormonal going on. This has never happen to me and I'm kinda depressed about it! It's making sex not so enjoyable anymore and I dont even want to get into sex because I feel like thier is no reason for me to, I just get upset trying and then not getting any satisfaction. I won't deny my hubby sex or anything and he is trying to be understanding but unless you have had this happen to you then you just know what this problem is like! Has this happen to anyone else and if so how did you fix it? Can anyone offer some good information ?
