Chastity and orgasm denial discussion

My boyfriend has been locked up now for 39 days (his record 42 days) in a CB6000. However, since we do not live together, there are times - a day here or there - where he is unsupervised AND unlocked, for work purposes. He swears that he is “being good”, and the only reason I don’t question him is because I know deep down that he truly wants long-term chastity/orgasm denial. Now of course I do wonder, am I being naive?? I hate to think he’s actually masturbating, as I do love the control and knowing he hasn’t cum. And I can only imagine the temptation, to which he succumbs, and then he perhaps can’t bring himself to tell Me as he doesn’t want to disappoint. Yet, I’d surely rather know! We’ve been together about 5 years now, and frequently incorporate chastity into our sex/alt lifestyle. It can definitely be a challenge for long-term, mainly because of family life - work,kids,financial stress, and the fact that we don’t live together. And then add in the unknown of the fact that he may not actually be chaste! It really pushes my buttons knowing that he is truly denied, and this uncertainty sort of dampens that feeling of power/control…
