Does looking at porn involving she males make you gay or bi (for guys)??

So i dated this guy and one day i was on his computer, i guess i was kinda snooping, and i found this video player on it. ALL the videos were porn which isnt really a problem, but they were all she male porn. My big problem with it was the way he hid it and acted like he didn't put it on his computer, but i knew it was him. He finally admitted that he was looking at it and he acting like it wasnt a big deal. Which i dont have a problem with porn but to me i kinda felt like he was hiding something from me like maybe he was gay or bi. He really wasn't in to sex that much, it never really lasted all that long maybe the longest we ever went was 20 mins. I watched one of the videos once and it was a dude fucking a chick with a dick in the ass and jerking the dude with boobs off. I asked him he how could he like this stuff when it involves to dicks, and just told me he didnt know that he was just weird. So anyway i could maybe see why a girl would want to fuck a she male, they could get a dick and play with tits at the same time. I just dont understand why a perfectly straight male would want to watch ass fucking with to dicks in the picture ALL the time. So if anyone could clear this up or has anything to say about this situation feel free to comment!!!!!
