Sexual stimuli temptation DAY 56!!

I’m currently on day 56 of no pmo. The first month was a breeze. I found it very easy and felt little temptation to relapse again. I was also able to sustain from porn substitutions such as ig models on Instagram. However the last couple of weeks particularly last week I have been noticing a greater urge to not watch Porn but to go and look at ig models and sexy videos. The other day I also typed in a pornstar on google and I truly thought I was just a click away before relapsing. However I was strong enough to exit without looking at anything damaging. I feel anything I see that is sexual stimulating starts to tear away at me and I don’t have the resistance I once had to abstain from such material.

Is anyone else having this problem and can someone tell me why I’m suddenly keep trying to seek these materials.
