husband watching transgender porn

My husband accidentally left his bowser history open a few days ago. All he had on there waa transgender porn, woman with penis or men looking like woman. I couldn't confront him about it. We been together for nearly 13 years and I am currently 22 weeks pregnant and I honestly am too afraid to accept the truth. Is he gay? Bisexual? or a face? he knows something is wrong with me because I don't let him hug me or kiss me. We haven't had sex in nearly a month. Now it makes me wonder if it's because I don't have what they do. I need help and advice.
