need some help here

hello brother and thanks you in advance for taking sometime to me in your answer
I am on day 36 and i am on flatline from last week i am having no urges for sex anymore but still i am getting random boner sometime .. example when i am talking with my lover but not about sexual things etc ...just simple talking on fb but i get boner while talking and sometime watching something in mobile and something pops up on the screen with little or dirty image then i i got erection....
so my question is that ...as i have read that no erection or boner during nofap flatline...or in my case what is going on is it normal or positive sign of recovery because i dont want to go back i i will complete as long as i can. please remember i i am on flatline getting erection ... experience people who have gone through same problem please elaborate..is it good sign or negative sign of recovery getting erection during flatline as i have told you my complete story

 

yes i am living my life but i i want to know does erection will take me back in this rebooting journey??
