Morning wood

So I feel very stupid for not knowing this but apparently when a guy has morning wood it doesnt mean they are horny. Am I really the only one that had no idea? Morning wood mostly means that a guy needs to pee unless they had a sexy dream or something. I only found out after a night with my bf and i wanted to play with him in the morning but he was like "oh im sorry that is just morning wood". Anyway if I helped km glad! Please comment if you have any thoughts!
