His and Her Health

Hello, I'm new here. Looking for someone to help me with my problem. I have never been able to orgasm, ever with oral , sex , vibrators nothing has finished the job.I have been married for 14 years and I'm 31 years old . I get very gooood sensations down there with a vibrator and my finger , I don't feel anything with his finger. I am wondering why I get the feelings ,like nerve tingling down my legs sometimes when I turn the vibrator on high and the feeling is good but bad to.to much for me to handle I can't not (jump ). It feels good , I try for about 20 to 30 minutes with the toy but then my clit is to senitive and I can't reach orgasm because then it is to much for me to handle . I tried a stimulating gel and I was going crasy with the vibrator and everywhere down there was so wet when my hushands penis went inside me, and my vagina felt so good and diffrent when he was in me . I want to masterbate everyday now, but all I get is this over welming sensation. What is the problem ? Please help!
