er, yes its completely normal, do you want us to turn gay with you being the exception? you can't choose who you find attractive, its all about what you do with that feeling, which when you are in a relationship is nothing other than the thought, "oh, shes quite fit. nice rack" or whatever. is he allowed to find celebrities attractive?
him flipping out if he finds out you find people attractive at work isn't justifiable either. wheres the trust girl... you both need to chill out.
