Hello I have been watching porn since about 12 I am currently 19 I always had some issues but not like this I used to not be able to finish or really enjoy sex when I was younger currently this year I noticed I had some sort of problems in may I wasn’t able to get hard at all I went no fap for 11 days in may and then I was able to get hard but it would go away last month i was able to stay hard and finish with my girl not sex tho I was on no cap on day 36 I do kinda see if I can get hard with out porn I don’t know if that’s messing up my journey but I am wondering how much longer until I am able to have sex I still get boners with my girl when making out but they will go away fast
