[PIED] Fantasizing set back my progress

Hi, i'm for now on a 42 days streak hard MODE and i suffer from severe PIED. I was fine but since the first day, my MW became more and more hard. One time, i got my first spontaneous erection being awake. So, after a rock hard erection the morning, i didn't started to fantasize about porn but on hookers i could call to "profit" of my erection during long minutes. In fact, i was really happy of this progress on my erections. However, the day after i didn't get a morning wood so i begin to stress : Does my fantasizes set bme back to day 1. If yes, i feel really depressed...
