Don’t know what to say😳

My boyfriend masturbates.. a lot..

Like everyday, but he tells me he doesn’t, at all and that he doesn’t need to. (Which I believed him because we have sex everyday sometimes even more than once, now that we live together)

I had to use his phone one day to look something up and that’s when I saw his search history, and now every time I use his phone and look I see that he watches porn whenever I leave the house basically.

It’s starting to bother me because now he’s lying about it and hiding it from me.

Last week I came home from running errands and walked in on him doing it 😦

And I feel like it’s starting to screw with our sex life because when I get home from work and want to do it, he’s not in the mood 😑

How do I talk to him about this without upsetting him?
