Welcome @firsty its nice to meet you 
Addiction to porn, masturbation, and sex is relatively common but many people feel ashamed or afraid to talk about it. It is a good first step to reach out for support.
Neal has a good list of sex / porn / love addiction support and recovery groups here:
You mentioned looking for mentorship - those groups are a great place to find it. I am in www.SA.org myself.
Here on TS there is an active community of folks in recovery from porn and masturbation, and there’s a pretty active thread here: PMO - Porn, Masturbation, Recovery. You can find more material by searching terms like “porn”, “PMO”, and related terms in the Talking Sober search bar (beside the magnifying glass symbol).
