My boyfriend hides my vibrator from me...

So let me explain....

We've been dating for over 3 years and he's always known I have a vibrator. He's tried to use it in me but it's just awkward so we stopped. He's never made me orgasm in 3 years of dating so I use it on myself sometimes just to be able to feel some pleasure once in a while...

A couple months ago we had a huge screaming fight about it, he felt threatened by it and wanted me to throw it away. I felt so insulted. I don't feel like it's my right to own a toy, but I do feel like it's my right to experience orgasms... since he cums every time and I never do. He literally just can't get me there no matter what we try, so I have to have something....

So for about a year now he's been putting it in this little bag with the batteries out and he checks on it when he's suspicious if I've used it.... I hear him and see him going through my stuff to make sure it hasn't been used...

A few nights ago he found the batteries in the bathroom so he went through my stuff again. But I moved it to a new place but I'm sure he'll find it again...

...Is this normal?? How do I get him to screw off about it? It's just a vibrator. I used to feel ashamed of myself but after 3 years of sex I just feel like I can't be the problem anymore. It's not my fault he can't make me orgasm.
