Thumbnails (possible triggers)

I have a question please be considerate to the answer as I already feel plenty of guilt and shame.

I have relapsed and I just want to know at what level of addiction I am...
I have and an addiction to "normal porn" however I am worried about the level of my transgression.
I know all porn is bad but I am feeling extreme guilt because I come across thumbnails that depict more deviant types of porn i.e. Group, lesbian, GB....
I never pick this videos... and I try to look away anytime they come across... and I have been trying really hard to abstain.. I just broke a 24 day streak... I know I have far more cautious and completely avoid all types of P.... but have I escalated because of these thumbnails?
I just want to know your guys opinion....

Thanks
