I sent a nude to a guy and I don’t know if I am gay

I am 19 and I have been battling with my sexuality for a little while and I have always been talking to someone about a possible hook up he asked me for a picture and I sent him a nude (this is on a gay hookup site). I have taken gay tests online and they say that I am bi I am not sure what to do I like to look at men and I like to watch gay porn sometimes but I don’t know if I am gay/bi
