Am I gay?

Me and my friend both go to high school and are heterosexual males, me and him have made multiple gay jokes implying that I'd give him head for a Wendy's frosty. I personally have a bit of an addiction towards frostys, and he is actually starting to consider make this deal a real thing. Would you consider it gay to accept this offer, considering how much I love frostys. I personally would not but I would like to see what you guys have to say.
