I am a straight man, I also have a girlfriend whom I want to marry in future. Once, I went to a porn site to explore different content. I came across gay stuff and while watching it for a couple of minutes, I got sexually aroused. I was really shocked. I am now confused about my sexual orientation. My question is that, is it normal for a straight person to get sexually aroused by watching gay content? Or, am I going to be bisexual/ gay?
