Jensen James is cute and can be JJ my best friend dont like her first name but both her fist and middle names start with J so she gose by JJ so go with what you like though

I think Jensen is so cool! Knowing he's a boy, I think most people would refrain from calling him Jen. Like they said, just let people know that you always call him Jensen. I know someone with a Matthew and an Andrew and have NEVER heard her call them anything else (like Matt, Andy, or Drew), and I know a Beverly who has never been called Bev. So, if you are consistent and set the record straight if needed, it shouldn't be a problem. Best wishes!
