GUYS do you cuddle with your best male friend?

So I have a roommate who has a best friend that comes over all the time. He and this best friend usually end up cuddling on the couch together and sleep in the same bed at night. One time his friend came over and just laid on on top of him and they hung out that way. When they are not together they are constantly either calling or texting each other, and usually spend every weekend together. Both of these guys talk about girls, and one of them has an extensive dating history. I have made the comment that they would make a good couple, however one of them said that they are not sexually attracted to each other.
My question is, is this "normal" straight male behavior? Or do you think one or both of them is gay?
