Female led relationships discussion

We are new to this and I had been mentioning male chastity to my girlfriend for some time. We had great sext the other night and afterwards she presented me with a steel chastity cage to wear. I have not been allowed to cum for a couple of days and I am beging her to remove it, she will not, I belive that she likes all of this and I not sure if I can handle this as I like to cum every day. Any advise to stay on track?
