Introductions discussion

Greetings everyone. I’m a newcomer here and would appreciate any guidance you can offer if you’re willing to share. Lately, I’ve taken an interest in chastity and am thrilled to begin my journey. The main piece of advice I need is figuring out how to get my girlfriend on board with the idea. I haven’t brought it up with her yet; I know this should be one of the first steps, but I worry she might misunderstand. I’m not shy about discussing these matters since asking her to peg me went over well and she was quite enthusiastic. However, I fear that requesting chastity from her might make her think I no longer desire sexual intimacy with her. I struggle significantly with porn addiction and masturbate almost every day, which are key reasons for wanting her to take charge. Could you please advise on the best way to introduce this topic or what preparatory steps I should consider? Thank you for your assistance The Changed
