This is some sharing for why I fap frequently lately. Few years back, I fapped because of the real urges and fantasies, which happen like once every two/three weeks or so. Lately, I started playing mobile games and everytime I failed, I fap. Unconsciously, my mind associated losing in game to fapping and it became a habit, which I hate so much. I’ve now in the verge of uninstalling most of my games. No game, no failure feeling, no fap. I hope this works.
Maybe ,your provlem is stress. bacuse losing games gives stress.
Try to meditate and Uninstall all yoyr games for a while
Yes, stress is the main issue. Game + postgrad research + covid era = stress.
