I dated a Pats fan for 2 years and it never really got in the way. Except last Thanksgiving she was at the massacre with me and was cheering the entire time. It got to the point where I looked her dead in the eyes and told her I was going to leave her at the stadium if she didn't shut up. She stopped cheering after that
Look at the bright side. You will be fucking a Pats fan constantly. Take a picture of her in a Pats uniform while she is giving you a BJ with your Jets jersey on. You will become an instant hit. All kidding aside, grow up man. You don't discuss such a thing on a football board. This is your private life and you can make your own life choices without us strangers chiming in.
I don't think we have the right stuff in our labs to make it. And I don't think I coukd have sex with her if she was wearing a Pats jersey. Major boner killer.
