Erections hard will back???

Hello everyone! I want to tell you my short story that brought me here. I never masturbated during my tender age. However around the age of 18 I masturbated prone for about 3 months looking at photos and sexy images of my ex, we had sexual conversations or webcams while I masturbated prone. When I left with her in September I completely stopped the stimulation and I remember having no more sexual stimulation or spontaneous erections. In January we came back together and started masturbating prone with less frequency because I always had webcams and sexual conversations. It was less frequent and was until mid-June. After mid-June I stopped all stimulation. In August I felt reborn, spontaneous and hard erections just looking at or talking to my new girlfriend, so much energy and so much security. I felt that my penis worked perfectly and was ready at all times. This lasted until October because I succumbed to my continual more and more angry erections like a normal 19-year-old boy. From October I masturbated prone and with my hand (more with the hand but without any lubricant!) while i looking sexy photo of my gf and talk dirty until June of this year. I quit on June 12th. Now I no longer have spontaneous erections even looking at sexual images, I get semi-erections just talking dirty with my new girlfriend (the one I had with angry erections) or talking on webcam and showing our parts. I've never masturbated in porn, but I don't know if I still have PIED or overmasturbation and if one day my angry casual erections will come back ... I really hope so. I always masturbated 2 or 3 times a day for the chaser effect, but I still spent months without jerking off ... I also ask for help because I'm afraid of having damaged something in my penis with prone masturbation ... Someone can answer to my questions? Will my spontaneous and angry erections return? How long will it take you according to you?Is it possible that my brain is no longer aroused with my girlfriend because I masturbated on her photos and on webcam until sexual exhaustion? I am on day 33 and have days when I feel it more alive and days when no, keep talking dirty with her in messages and on webcam can prevent my reboot? Should I avoid seeing it hot in the webcam? Especially if he has experience and knows what it means to feel like this and he is cured ... Thank you very much !!!
