I've never orgasmed and I'm starting to get really frustrated. I know what I enjoy, direct clitoral stimulation, my favorite is clockwise swirls. I tried a vibrator a couple times, but it actually turned me off. I'd really appreciate some help. Every time I try I get hornier and more frustrated. I basically get to the point where my knees are shaking and my vagina is contesting, but then it just stops building and I'm stuck.
