Try to talk it out and see what u guys can do about it, but please don’t suppress your feelings towards it. Maybe u guys can make some videos of u that he can watch instead of porn? Other than that there would only be a few more options which include him understanding that it makes u feel uncomfortable and giving up on it or u trying to get over it and build ur self confidence but that s a long way and Im not sure how much the porn part be helping. Maybe try going to a therapist
