Please Help... First Timer

This is the first time I've ever even spoke about this. I have watched porn and masturbated since about the age of 14, im 22 now. never more than once or twice a day .. 3-5 days a week. Ended up with my highschool sweetheart and we are now going on 6 years. However, we both lost our virginitys together 3 years in and I had trouble getting it up even then but I managed. After this , for almost months I Just couldnt seem to get it up.... Fell into a deep depression. I Also smoked marijuana most of my teenage years and for some reason after I stopped I was able to get an erection everytime. I Dont believe it was the weed but me keeping it from her and feeling bad. So when we jumped into sex I would just have constant thoughts, never focused and couldnt perform. It started taking a toll on our relationship and after I failed the first time it just kept eating at me. This was 3-4 years ago .. and havent had problems again until now. I stopped watching porn and Im attempting NoFap, its been about 3 days but now i have no sex-drive.. someone please help.

PS- My girlfriend is supportive of me when im unable to perform but its beginning to take a toll on me please help
