sex leads to pm?

Overthinking, I would say. This time period of increased urges always happens to me after sex for approximately 2 weeks. You just need to be strong, it is a dangerous time for us people in long distance relationships as we don't have sex on a regular basis.

 

In this case, I guess it must be just regular porn addiction still living within us. You need to remind yourself on daily basis:

Will acting on this temptation bring me long-term satisfaction or instant gratification?
What will be the end result if I act on this temptation?
If I choose to act on this temptation will it make my life better or worse?
Do I take 100% responsibility for my own actions or do I blame others and make excuses?
Can the addicted part of my brain force me to act out against my will?

Stay strong m8! Do your best to fight this addiction.

 

Then there is not as much to worry about as porn is the main enemy here. As long as you can avoid porn you are fine. Depending on your own personal approach to nofap (easy, normal or hard mode) just do your best to avoid masturbation next time. Look at the questions I've to send you, they do apply both to porn and masturbation. Perpahs try to change this habit to something else, exercise, play games, read books do whatever you like, but PMO.

 

find some project to redirect your sexual energy to, when your girlfriend is not around.
