So i have been with my man for almost 2 years now and living with him for almost a year. I have always had issues with him about being on his phone all the time even taking it to the bathroom with him. one day we fought so bad he left it home so i decided to go through the history on his phone and found gay porno sites. I did confront him about it and he said it just poped up when he was searching other things... I did not believe that. he left his phone at home again so i went further into his history and found more times he looked up gay porn. when he came home I left him a letter cuz I'm not good at asking questions or expressing how I feel on certain things. So he read the letter n said he just looked it up n that was it. So i grew the balls and asked him if he has ever had intercourse with another man n he asked why.. of course I said i need to know. he said that he did one time when he was like 17. he said a man just started to touch him n it turned him on n that was the only time it ever happened. I asked him if he liked it and if that was the reason he was looking up the gay porno n he said no that he did not like at all and that he is not gay and he promised he would never look it up again. I don't know what to believe? Can i get some advice.
