Is it gay to shower and sleep with my friends?

Hey, so I'm 16 and I have two really good friends, their both 15 (their twin brothers). We play football and have been for six years, usually after football games on friday's we come back to my house, and I have a huge walkin shower in my bedroom so we all shower together and they spend the night, do you guys think were gay? all three of us sleep in the same bed by the way.
