porn on my boyfriend phone

Lovely
I don't normally go through my hubbys phone but ever since I got pregnant he barely touches me. We went from 4 or 5 times a week or more to maybe 1 time a week 2 if I'm lucky 3 if I beg!!! 
I went through his phone (I know I know shame on me) he's been watching porn! 
I'm a VERY sexual person and I do all kinds of kinky things for and to him. 
Am I just not enough? Should I be worried ?? We've never ever even watched porn together ! I've never seen him watch porn . We never even talked about it . 
Help !
