Is it normal to not be able to say your name?

Is it normal to not be able to say your name? I’m 22, and for some odd reason, everytime I get asked what’s my name, I have a block and I’m unable to say my name. In high school and college, I’ve been able to get it out much smoother but I would always hear laughs from other students because of how much of a stuggle it was to pronounce it and it made it seem I forgot my name. Ever since i graduated college and I started full time work, my name is impossible to spit out. My name is John so it’s not hard to pronounce. I’m just curious does anyone else have the same problem and what did you do to cope with it?
