Need some advice

Hi, am in day 23 without PM... the last few days i have no morning woods, no interest in PM, full of begative thoughts and fear about sex.. i never had real sex in my life yet.. Yesterday i got wet dreams twice in a night. After that my dick is like no power and a kind of numbness and i cant feel any sensitivity... but in the afternoon I got erection for few seconds, i thought the nofab is working... but now am trying to erection without thinking about porn, its not working.... Am I experiencing flatline phase... and how long it will continue usually... its very hard for me to continue.. because of the less sensitivity in my dick i frequently trying to touch it and trying to get erection... please give me some motivation and advice... If i try to get erection without thinking porn and thinking about my girl is good? ... Is that ok ?
