Very weird thing. I need some help

So I will try to be as brief as possible. I jelqed for the first time, and for 2 days all was fine. I warmed up for 10 minutes and did very low intensity workout. As soon as I fell asleep after the second day, a few times a night I was woken because my entire pelvic and base of the penis area “flexed”. Basically spasmed very hard making my entire hip shoot to the roof.

It wasn’t painful or anything and it felt more sore if anything. I did not have a morning erection but during the day the weird feeling passed and my erections and libido shot through the roof and now my erections are rock hard. Have no idea if this is good or bad

Thanks guys.
