Major stamina increase after first 4 days locked up.

That was a surprising result. I was locked for a full 4 days and hadn't cum in almost 6. I always cum 1 to 4 times a day so it was wrecking my head and balls. My stamina went from seconds to 3 and even 10 minutes. Anyone experience this or understand it?

Before chastity I had months of pretty severe PE , cumming with me wife always within a minute. Jerking off was also with a minute. To be honest I was loving the humiliation of the PE. I was even practicing to be quicker and it was reducing the times dramatically. My wife said she found it funny and sexy so I rolled with it.

My wife really enjoyed the lockup and had 4 orgasms over the 4 days, 2 times with me involved and 2 time me just lying next to her. I really enjoyed being locked up and was getting more and more into it.

Last night in bed my wife said to unlock, she missed my dick and we would have sex in the morning. I said that's a bad idea, that I will not be able to stop myself from jerking off after almost 6 days of not cumming. She said, okay lets have sex now. Her loose pussy was crazy wet so I slipped straight in. It was very intense but I didn't feel the usual "i'm going to blow quickly" sparks. I was able to fuck her hard for a good 3 minutes which is really, really long for me. I thought I would cum super quick but it was the opposite.

I always jerk off at night even after sex but I had zero interest. This was also a big change. In the morning we had sex again and for the first time in maybe 6 months I was able to last about 10 minutes. I fucked my wife's big loose pussy hard and even had to look for my orgasm.
