Hopefully, you read this!

Hello, everyone!
To begin with, my name is Dave; I am 19 years old and currently study at a university as a third year student. I cannot really say fapping has proven itself detrimental, but I still want to join the cause for several reasons:
1) I want to eradicate this addiction as a whole
2) From what I have heard, nofap can actually somewhat help the facial hair growth and when it comes to mine, it's a mess is all
3) Because I am severely depressed after getting rejected by a girl I had feelings for, I feel this whole thing just adds up to turn my life into a mess (for what it's worth, I am doing just great at academics but no so great in social life)
Thus, tomorrow, I am planning to embark on this uneasy journey, but I am in need of your help. I cannot help but notice that I can get erections and precum while in public spaces with a lot of attractive females and although some people claim that it does not count as a relapse, it still feels like I have failed. As mentioned in 2nd point, I am in it for probable facial hair growth, so testosterone should - at least in my opinion - play some role in it. I also feel like I am getting easily exhausted but the MOST IMPORTANT reason for why I want to begin this whole thing is to be more confident with girls that I meet (I am a silent type of a person, which might have served as a reason for why I might have lost the chance to get close to the girl but anyhoo..)
Cutting straight to the chase, I want to know what exactly counts as a relapse in my case. I can tell you that I have completely cut off porn but erections with precum (sorry for the graphic details) are still there. As a matter of fact, I relapsed 5 minutes before creating this thread, so I am in a desperate need of help advices here. All in all, I hope one day, after reaching the first month without fapping, I can create a thread on improvements that I will have attained.
Thank you for sparing your time and reading this!
