Am I in the wrong?

My boyfriend watches porn, hes cheated before, and even paid some girl $30 for a sexy video before. I just feel like I'm not enough for him, whenever I find the porn on his phone. And it's even on days where I offer to "satisfy him myself" but he rejects me and uses porn instead. Am I wrong for being uncomfortable and feeling grossed out by this?

He also does this basically every single day when he's "showering" for like 2 damn hours.

Opinions needed. TIA
