Joined because of porn induced erectile dysfunction

@Ron Bigley, welcome to NoFap where you are amongst friends who are here to encourage you and not judge you.

Congratulations on not M'ing for two weeks! That's great.

To answer your questions:

1. This is going to be your call. There are some who believe M is fine while going through rebooting as long as you don't use P. There are others, myself included, who feel during the rebooting process, it is better to abstain from both to completely reset yourself back to factory settings.
2. This goes with your choice from the answer above. If you choose the abstain from M, you would abstain the duration of however long you choose for rebooting. (Yes, it is possible not to M that long so don't believe you cannot last that long.)
3. Work on you before attempting to bring someone else into your world right now. In the process, many gain a level of confidence not believed existed before.

What are your current strategies for combating the enemy called PMO?

 

There is no exact science to to this because everyone is different; how long you have engaged in PMO, how long your sessions each time, what you are escaping or searching for comfort, the type of P you watch, etc. 6-8 is usually the time it takes to form new habits but. Any have found 90-days is a good goal to strive for to change your existing habits. Because you used P to M, the chances are greater that you will be drawn back to P if you continue M which will extend the time it will take to reach 90-days of sobriety. Because you haven't used PMO for that long, it may be easier but it may also be more difficult because you began during the beginning of puberty. Make no mistake even if if is easier does not mean it is easy. If it were easy, you wouldn't be here.

Based on what I have just written, I cannot give you a day estimate of changing any variable. You will have to pick a a direction and begin and if that doesn't work, change along the way but if you change, change only once.

Your confidence comes with accomplishment as well as becoming freer from addiction. As you accomplish days and weeks of sobriety you will begin to have the confidence of knowing you can do what you believed you could not previously do. Also as you free yourself from the grip of addiction, you may gain a confidence that was never there. Oftentimes guys will buy into the lie that unless you look like the guys in porn you will not have success with talking to girls. Do looks matter? Yes, to a degree but what girls, even those who may not be most attracted to you like more than anything else, is confidence.

Gain confidence from this huge accomplishment you will have.

That is going to have to be a personal decision. The frustration you are experiencing will be there whether you have exams or not. As you get closer to your exams, your stress level will continue to rise and using M to calm your nerves may not always be available. Since these are your exams. I cannot take the responsibility of telling you which decision to make but encourage you whichever decision you choose.
