How would you react if your boyfriend was secretly gay?

I found a small luggage bag hidden in a closet after I moved in with my boyfriend.. In side wear girls panties with a hole cut out in front. Cut off wrangler short shorts.. Make-up glitter ect.. And a video of himself having sex with dildo's.. He says he isn't gay that he just used that as a way to satisfy himself cause he had been hurt so bad in the past that he didn't want anyone and that worked for him.. A year later while trying to fix a problem with computer I found a message that didn't get delivered to a friend (that is a girl) that he wanted her boyfriend to squirt cum all over her face... Is he gay???
