boyfriend/issues

wanting opinions on a couple nights ago.

bf comes to bed, turns porn on phone starts masterbating.

I leave him to it, maybe hes tired and just wants a quick release idk

30 mins later... still goin

so I ask "do you just wanna have sex" he says no he just wants to do what hes doin....

an hour and a half later, I go to the couch, hes still goin.

next morning wakes me upx everythings normal, like nothing happened....

ideas? is it me? porn issue? masterbation issue? ugh...
