I am 18 years old and before when I use to watch porn, my erections came instantaneously but now I have to masturbate a bit to get them. If I don't stimulate my penis my erection will go away in like 30seconds to 1minute... can anyone explain to me what is this? Is it age that made it difficult to get erect because that period when the erections came instant I was like 14,15 and 16!

Are you otherwise healthy?

I think so... haven't checked with a doctor in a while

It's not so much age as it is loss of visual stimuli. You've been watching porn, and porn gets old fast. It's not surprising that porn alone doesn't do it for you anymore.

Porn isn't very realistic when it comes to sex. It can be a turn on, if used in moderation, but like most things, too much makes you less prone to its effects.

If you're healthy, and there's nothing medically wrong, then I'd say that porn is just growing old for you. It's no longer a thrill.

I agree with everything alty says.

Take a break from it for a while and see hw that works for you.
