Why Does My Penis Become Sore After Ejaculation, Regardless Of Duration Or Intensity Of Sex, And Take Hours To Recover For The Next Erection?

Hello, Why my penis gets sore after ejaculation? I first thought it may be because of having sex for long time. but is not. I experimented multiple ways like went for 1- Having ejaculation after few days to have release in as less thrust as possible. it took me 5 thrust. 2 - Even I tried with 1 shot ejaculation during sex. Still my penis get sore. Normally PIV session last 10-15 mins. but I tried the above for cause. It does not matter whether i have sex for 1 thrust or 10-15 min long session. My penis get s sore. Normally it recoves back in 30 mins but i can t have another erection in next 3-4 hours.
