Hard Ons and Prostate Drainage

I’m just going to be locked up when no one is around for a short period. It’s been six days without an orgasm, which sets my personal record. I’ve noticed the “blue balls” sensation has become constant and gets about an hour worse after getting hard. This seems normal to me, but how long until it fades away or is it permanent? Does being locked 24/7 prevent erections enough so you don’t feel it as much? Also, my keyholder enjoys a rougher dynamic with me but hates anything anal-related. So I miss out on prostate milking and other release methods; only orgasm counts for relief. Plus, I’m not permitted to do it myself. Without any release for an unknown duration at her whim, will this cause damage? People say nocturnal emissions handle the buildup, though I’ve never had one that I know of. What does everyone think?
