Question about erection, read details for complete question

[Boyaca]

I am young, and I do sadly watch porn on a regular basis. Maybe once a day or so maybe twice sometimes. But now I have a problem.
Going to try to make it short:

We went to a camp with school, and all the girls were getting all sexual and stuff and tbh I ain't the guy to be random hooking with girls. But this one girl, I had already earlier had a crush on. She was twerking and lapdancing etc. Me and her have know eachother for 3 years, thanks to school. But now we are like getting really close after this camp stuff cause we was talking to eachother alone etc and just happened to be that when I got home we started texting and I found out she also liked me...

Here comes the problem, on Monday (tomorrow) we are having this party and she wants to "kiss me", "touch me" and "get it on" and it maybe will be the first time "I get lucky". She already told me that I will be the only one that is going to get a lapdance from her :)  But when we had the camp (not long ago) I didn't get an erection when she nor the other girls were dancing. Even if they are very hot and got sexual and close to me etc...

Now I do watch porn and masturbate, but I have quit for 5 days or so now and I'm trying to keep the streak up so I can permanently end it. Because I cannot stand how hard it is for me to get erections and I just feel horrible after i climax...
But every time I quit IT BECOMES EVEN HARDER to get an erection outside of porn.... since it's tomorrow I am considering masturbating today in hope of increasing my chances of getting a hard good erection since when I haven't watched porn or masturbated in a while it become more soft and I climax really easily. I am afraid that it is going to be akward or embarrassing if we "get it on" and I won't be able to get a good erection.

So the question is; Should I masturbate today in hope of increasing my chances to a good erection or just hope for the best whilst keeping up my streak?

Side note: This is the first time on this forum, I do need an answer quick since the party is tomorrow.. I don't know if the title was good and stuff...

You don't mention your age, but is there any adult supervision at this school camp?  Anyway, do you wake up with an erection most mornings?  It is good to cut back some on the porn and masturbation, but you may be suffering from the pressure to perform with this particular girl.  Jumping right into intercourse may lead to disappointment.  If you have feelings for this girl, talk, kiss, and hug, but do not necessarily think that you need to rush into ultimate sex with her at the outset.  Give things time to develop.  She may even be glad that you want to slow things down a bit.
