Chastity and orgasm denial discussion

So I wasn’t really the ‘bull’ in our cuckold/bull setup. But if I may say so myself, I was pretty excellent at sex. Back then, I could maintain intercourse for a good stretch and do it multiple times each night.

Since my fiancée and I started with chastity, though, my ability to ‘last’—let’s use that word—has dropped significantly. If I can manage four minutes nowadays, I’ll be satisfied. And when I’m finally permitted to ejaculate (whether ruined or not), I am completely exhausted. My recovery time has gone downhill.

I suppose this is likely the same for many men in chastity; our skills as standard lovers are bound to decline. Yet my fiancée still desires a ‘good f**king’ every now and then. We own a strap-on, but she says ‘it’s not quite the same.’ We have rabbits and wands too, yet she insists they don’t compare to a cock. I know what many of you are thinking: Cuckolding is the obvious solution, but she claims she could never do it (and honestly, while I find the fantasy appealing, I’m unsure if I could handle the reality).

We have had a small experiment over the last few weeks, returning to vanilla sex. I believe she wanted to ensure that without denial, I remained caring and affectionate, while I want to try regaining my stamina.

The outcome? I was still affectionate, her needs were prioritized (admittedly not quite as much before, but my decline was slight enough to be manageable). My stamina, however, though it has gradually risen over these weeks, is still far from the endurance I had previously. Female domination has slowly crept back into our dynamic, and now I am denied again, for an undisclosed duration. Not that I mind!

I realize this reads more like a statement than a question, so my main point is… have any other couples (or individuals) faced similar issues? And how did they resolve them?
