My new girlfriend is into orgasm denial.

She loves bringing me to the brink of cumming, but then she stops. She has given me a blowjob every day this past week, but she never finishes it. She stops right before I'm about to cum and then denies me consent to have sex. We haven't had sex since last Saturday, but she constantly talks about it. She encourages me to watch porn with her. She lets me watch her use her vibrator. It's like her goal is to keep me horny, in a constant state of arousal.

It's driving me fucking nuts.
What do?
