Men and the bathroom

Does anybody else's man spend an incredibly long amount of time in the bathroom? I don't understand why they take so damn long multiple times a day. Mine spends about at least an hour sometimes two hours and he always locks the door. He will bring his phone with him sometimes, but there's times his phone was dead and he was still in there for two hours. Do they lose track of time? The bathroom is not a man cave. I don't know if this is something i can deal with for the rest of my life. It's different if they actually have bowel issues or if they're just in there screwing around. I feel like it's not normal and they could always have something to hide. Especially when you don't live together and they get plenty of "me" time.
