Is it normal to be annoyed...

Is it normal to be super annoyed with all the "straight" men who say they are straight but have a desire to have sex with another man? Is it just me or is anyone else irritated by that? I believe that if you're straight you would have NO desire to have sex with another man or want to give a BJ to or get a BJ from another man. It may not make you gay if you have that desire but you certainly aren't straight. So is it normal to be bothered by a man saying he's straight but wanting sex with another man?
