First chastity device arrives tomorrow.. Expectations and advice?

Hello everyone, I’m a newcomer here and I think I’ll be sticking around because I really enjoy it (: Tomorrow is the day my first CB-6000 arrives, and once I have one last orgasm, I need to get locked in. My girlfriend and I are both 18 years old. We’ve been discussing chastity for quite some time now, though she hasn’t gone into too much detail.. So, what should or could I expect? Real life
