Pied not cured yet, 31days no PMO!

Hi, I'm 19....I'm in a relationship, it's been about a year now...i really love her soo much...so the first time we tried having sex, i didn't get an erection...i was shocked and scared as this had never happened when i watched porn, i found out this forum, searched and found out about Pied and self diagnosed that i have pied...I was on NoFap hard mode for 31days but today things went a little far and we tried having sex but i didn't get erect....

Spoiler: * Possibly triggering text !*

better erection than before but when she grabbed my penis, i lost my erection while she was sucking it...

I'm really clueless if I'm on the right track or not...please someone help me....i really love this girl! She became really quiet after this incident and I'm really scared what she might think. Please help!!!!
