HELP!

Okay... so. I'm a highly sexual individual. like.... HIGHLY. My partner, not as much. Doing it myself has completely lost it's magic and I haven't had sex in a month now. How do I go about bringing this up to her? Because I can't take it ANYMORE. Im incredibly irritable, my self-confidence is down from 100 to zero, LITERALLY everything makes me upset. I need some affection, but how do I go about explaining this to my partner without making her feel like she's not enough? OTHER than the zero sex we have an amazing relationship. But I can't handle it anymore.
