Is this cheating??

About a year after we got married, I stalked my husband's Tik Tok account out of curiosity. I found that every single account that he was following was of womens "soft porn" account's and he was also liking said videos. This encouraged me to check his Instagram account to which I found him liking his girl friends and exs bikini photos. I brought it up, said it was hurtful and it stopped. Recently for the first time I went through my husband's phone searching for photos of our son. I have never gone in his phone and have been with him for over 5 years. What I found broke my heart. Instead of finding photos of my son I noticed saved photos through his camera roll of naked women from the internet and screenshots of soft porn accounts that he's found. There were no photos of us. This prompted me to search his entire phone. His search history on Facebook, Instagram, Twitter and Tik Tok. I found it was all soft porn searches and of his exs and girls that he knows. Then I hoped onto his Google history and found him searching things like I've gotten fat although he married me at this weight. I also found so much porn. I brought this up with him and he changed his passcode to his phone so that I can't go through it again. Was I wrong? I feel cheated on.
