Dating the chubby guy

So me and my best friend, the chubby guy, have been best friends for years and we have been contemplating dating for the past couple weeks. Everyone thinks we are perfect for each other, to be honsest I think so too, but I’m really self conscious on everything I do, and I don’t want to be known as the girl who dates the chubby guy. Am I just going crazy! Please anyone I need help!!!!!!!!
