Chastity and orgasm denial discussion

for those who have ever tried chastity will have exciting time but probably at the same time, the difficult time as well. I have recently met a local woman who is interested in putting me into chastity, she is not a professional domme as well, which makes me so excited. However, she suggests that if I want to be her slave, to ensure her safety and that I always know who is in charge around, I have to wear a chastity device for her during our relationship or everything will be over and she will not see me again. However, it’s always a super great fantasy but reality is so difficult. I was once locked in my chastity tube continuously for four days and I remember I did not have any fun on the 3rd day and it was all pain on the 4th day and I released myself on the 5th day and I masturbated vigorously… In simple terms, how do you manage the difficult time when you are in chastity?
