18M – erection works during masturbation but not with real-life thoughts, confused

Hey guys,
I’m 18 and trying to quit masturbation. I don’t watch porn, but I’ve been masturbating for years.

I recently noticed that I can stay erect for as long as i want normally while masturbating, but in real-life situations (like when a woman is close), I struggle to get aroused. I understand this is not any disease, nerve damage, or real ED, but more of a porn/masturbation conditioning issue that can improve by abstaining and letting the brain reset.

My lifestyle is good:

• Regular workouts
• Healthy diet
• Proper sleep

Masturbation is just one habit I’m trying to fix, and self-control is still a challenge.

If anyone has gone through something similar:

• How long did recovery take?
• Any practical tips to stay consistent?

Looking for real experiences and support. Thanks.
