Frustrated

I am so incredibly sexually frustrated and I don't know what to do about it. My wife and I very very rarely have sex. She has such a low sex drive that we've only had sex 3 times in almost two months. We have had so many talks about it that I don't feel comfortable bringing it up anymore because I don't want to make her feel bad. We've tried new things. Use toys. Experimented with rougher sex, which I've always loved..she's not a fan. She just doesn't need or appreciate sex like I do. It's making me testy, which I feel bad about...but I'm so horny..which sounds so freakin lame to say. But I'm losing my mind. My dildo has become my best friend. I want sex. I want it. I want it so bad.
