Is it normal for a boy to cry ?

My friend was having a party at her house. Her friend brought the movie Max to watch. It's about this dog who's friend got killed in the war after that the dog was sent home to the boys brother but was suppose to die. Her friend started crying a few minutes into the movie. He cried right after the boy got killed. He was crying so hard he couldn't stop he even picked up her dog and hugged it. Her friend said she's never seen a boy cry before she thought since he was cute and she had a secret crush on him she thought it be cute to see him cry which is why she brought the movie. She was laughing at him because she thought it was cute. She didn't even feel sorry for him. I sure did. I wish I could have done something to help him feel better. Since he's gay I didn't know what to do. If he liked girls I would have held him and gave him a big hug. I just sat next to him and rubbed his back a little. He finally calmed down. Plus the dog was helping him too. He jumped on him and licked him it made him feel a little better. I can't belive she did that to him poor guy. He's been so nice to her. I don't know what made her do that. She's probably upset with him for being gay since she had a huge crush and obsession with him she wanted to get back at him. I feel sorry for him I wish there was more I could have said or done for him. It's not that funny when a boy cries it hurts me so much especailly since he's my best friend. He said he's never even seen that movie until now. He didn't think it would be sad. He watched the rest of it but towards the end he was crying like a little baby because the dog got shot almost died. I'm not saying it to be mean but he did and he told me his heart was broken he didn't stop crying until it was over. Then he told me how sad it was. He had tears in his eyes the whole show. Even the song at the end was sad. It was the song Forever Young Blake Shelton sang it it showed pictures of soldiers with they're dogs. It even showed Max when he was a baby puppy. It was a cute movie but sad I even cried a little. I wanted to cry in his arms but I knew he wouldn't let me since I'm a girl and he likes only guys. I did lean on his shoulder a little but I had to be brave for him if he saw me cry he would cry even more I don't wanna hurt him. Even though I was teared up too. My friend made both of us watch it she didn't even sit and watch she was outside visiting with our other friends. I don't know why she did that to us. It's almost 3:30 in the morning I'm still crying my heart out. My friend is staying with me. He's sleeping on the couch I want to go laid next to him but I'm worried he might not want me to. Like I said he only likes guys now. Is it normal for a boy to cry ? Is it ok if I go and sleep with him ?
