Is my bf hiding something?

Hi basically for a while now I been accusing my bf of being gay and putting it into his head I don't no why. But I looked on his iPhone one day and his history had some gay porn I mentioned it to him and he was denying it and stuff. He told me he has watched gay porn before he was with me . But never sins he has been with mew . I think I have made him curoiuse I'm not sure what I have done so much to make him try and prove himself to me he is not gay even though he has looked at gay porn he is in alot of senile about the subject . He also said he was curoiuse before he was with me cause he had never been in love before now he has been in love he noes . I'm confused I been accusing him of being gay now he's looking at gay porn but telling me it's disgusting and he isn't gay and could never do nothing with a man apart from get his dick sucked if he was desperate one day ..... Help ????
