Sudden premature ejaculation

Sudden premature ejaculation

I'm 20y, i'm in a relationship, at the first times of our relationship i used to bust in 20-30 minutes, now, when we moved in together i do it in 5 minutes, what's the thing behind that?

I did some abductors at the gym, i broke my pelvis? I'm very concerned, it's like a have a big sensitivity in my penis, some kind of itch, tickling, in the head, base of the head. And that tickling makes me bust faster

(No signs of any disease, i only did it with protection, no infection)
