Is it normal to have premature ejaculation the first time you have sex?

Thanks!

I KNOW SOME ONE CLOSE TO ME WHO SAYS HE HAS A BALL LIKE GROWTH DIRECTLY UNDER HIS TESTICLES BUT HE’S SCARED TO GO TO THE HOSPITIAL FOR FEAR OF THE WORST. I ASKED HIM IF HE THINKS IT’S SOMETHING SEXUALLY TRANSMITTED AN HE SAYS HE’S POSITIVE IT’S NOTHING SEXUALLY TRANSMITTED. IF ANYONE KNOWS THE FIRST SIGNS OF PROSTATE CANCER OR THE SYMPTOMS PLEASE LET ME KNOW.

im 30 just tried milking my prostate i read that there is health benefits from this i could see how it felt nice but no ejaculation? was trying to do it myself dont wanna go to doctor unless wo,man my girlfriend alaways wants me to i tried didnt work i wanna do it myself or have female dr experience before i do it with gf

Let’s say you’re abstinent for 6 years but all of a sudden you notice something wrong like inflammation, tenderness in the upper V area. Could it be an STD that first shows symptoms 6 years after s*x?

Please don’t bother responding if it’s just to say see a doctor. Thanks.

Like the title says, how long after first contact with an STD does a person become contagious, assuming they have been infected?
