One time when I was watching something erotic I couldn't help myself. I started scrolling through my gallery and saw a picture of my girlfriend, staring at it got me turned on and I started rubbing one out. I nutted quicker than usual. The first time I did this I was ashamed of myself, but later I find myself scrolling through her photos and jerking off to it it's pathetic. I've done this numerous times now and I can't stop, not even guilt can stop me. I hid all her photos from my gallery now and hoping to seek advice here on how to stop this habit of mine.

I promised to myself that I wouldn't sexualize her, I won't ever look at her with lust yet here I am at rock bottom trying to stop myself from going further down.

Edit: we're new to this whole relationship stuff, we've known each other for over 5 years and we're both our firsts. Which is why I'm scared over the thought of her getting turned off by my actions.
