What Would You Do? (Read Description)

Omg so I’m 16 and my bf is 18. Lately when we’ve been having sex he goes soft or sometimes can’t even get hard. Or he’ll get hard and the next second he’ll go soft. It’s making me feel so self conscious... like I just can’t make him hard anymore. My bf jerks off a lot and he says he’s gonna try to cut back and see if that helps. I’m really hurt rn cause we were trying to have sex but he went soft and then said we should watch porn to make him hard. Like wtf I got rlly pissed and upset cause now my bf needs porn instead of just being with me. What do I do.
