I will not give up

Hi. Former fapstranaut here and before this huge relapse vie gone 60 days without masturbating. Currently however after meeting my gf and having casual sex over multiple occasions it is hard to keep away from porn now that i have broken up with her. I've been masturbating day by day and i cannot get away from it. Ive come back to restore order and peace. I would like to try hard and regain my self control.
Currently I am aiming for 40 days and I will be sure not to masturbate
