Hello, Why My Penis Gets Sore After Ejaculation? I First

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.
