Denial , both turned on and scared

My girlfriend and I are gradually discovering the denial world. It started with some tease and denial when she teases me when we go to bed but do not allow me to cum. Then we bought a chastity cage and after 6 months without using it it is no a (small ) part of our sex life during foreplays. I suggested to my girlfriend that I would like her to have more control over my orgasm but she told me that she is afraid of going « too far ». In fact, it is the same for me I am very excited but also afraid of this chastity thing, I cannot see myself being locked at work and I don’t know how long I can be denied an orgasm without cheating when I am alone … Any advice for us on how to keep going in that direction smoothly and having fun ?
