20 y/0 female, new here

For years and years I have been in the heaviest denial that anything I was doing was wrong (lying, masturbation, and overall not being the best person). Nothing I was doing ever seemed to be "bad" to me, until I fell in love about 7 months ago. I now feel guilt about lying, which led to tell her the whole honest truth about everything I had ever lied to her about, that went extremely well. We are in a non-sexual relationship (aside from making out, and enjoying each others physiques.) and it is working well for both of us. She does not know that I have an addiction to masturbation, and I never thought I would either. It always seemed so normal. I have watched porn a few times but most of the time it is just my thoughts. I desperately want masturbation and lying out of my life for good. Recently I have decided to face all my demons, big or small.. so I found myself here. Any advice would be greatly appreciated, and my apologies if I'm doing this wrong.

With love, x
