any guys new to urethral play?

So any time i type urethral play in on any porn site i’m met with dude shoving crowbars down there cocks till they hit there balls. the tip of my dick is sensitive especially my dick “lips” and i kinda wanna try prodding my dick hole. however i’ve had a catheter placed in me for a night when I was hospitalized and for like a week peeing was super painfull. so your prolly wondering why try the penis plug thing anyway? well one time i came a really thick load. so thick that i actually pulled cum from my dick after i came. i pulled like three inches of cum after cumming and it felt amazing while i was doing it. like i was cumming a second time. so i wanna try the penis plug thing in hope to expand sexual pleasure. also for those who what i’m talking about when i say “pulling cum” how do i do that again. it was one magical load i can’t seem repeat
