Getting a crush while in a serious relationship

[humdinger]

Guys and Gals -

I don't post a lot here but I hear that this OOT place is a wealth of information

For those of you who are in serious relationships (like, say, roughly more than 8 months give or take)...do you or your significant other (husband, wife, boyfriend, girlfriend, goat, etc) ever get crushes on somebody new?

Let me clarify...not the urge to cheat at all, but more than 's/he's cute'.

Is getting a crush 'okay', and would you tell your significant other?

Thanks a lot guys,
