There is a book called 5 languages of love. I think this is your language of love.

"Words of Affirmation"

Actions don’t always speak louder than words. If this is your love language, unsolicited compliments mean the world to you. Hearing the words, “I love you,” are important—hearing the reasons behind that love sends your spirits skyward. Insults can leave you shattered and are not easily forgotten.


So...in theory.... you require nice words to be said from your boyfriend about you. This helps you feel solidified in how he loves you. With him simply stating "i don't have to back myself up because you should know that i would never cheat" doesn't quite give you closure. You need to hear the reasons WHY and get that affirmation. You need to hear WHY he looks at porn. You need to hear his reasoning WHY he thinks you are more attractive than those porn stars. You need to hear WHY he gets pleasure from masterbating instead of sex with you. Your boyfriends personality or "language of love" may be very different than yours and that "words of affirmation" is non-sense to him. This is a big clash and will point to a lot of differences in how you two communicate with other topics and arguments that will arise in the future.
