Help me, I'm new to the nofap and I have questions

Hello good, I am new in this state of nofap, I tell you that I am suffering from erectile dysfunction by pornography and I have noticed because now I have a partner and I do not get an erection, I have not seen it for a month and I have many doubts, so if you can help, I wanted to know how long it takes to recover to get erections normally, and I would also like to know if I have to go to ask for
Penile stimulation medication
or a psychologist to prescribe this medication to have sex temporarily, because if not my girl leaves me if you have to wait 6 months or more for my recovery, thank you for helping me who does
