Is it normal to have a crush on another person even though you have a lover?

Of course not, having a crush on somebody else is not cheating on your lover. As long as it does not develop into more deep feelings, it's okay to have crushes. I do have lots of crushes aside from my partner and he understands it as it never been an issue in our relationship. Well, he has crushes ,too and I don't mind as long as it's ONLY A CRUSH.

Hello friend actually it is normal to a person to admire or other word is crush but you must aware or we must aware and limitation only for admire and crush. But if you have beyond that you are cheating to your partner or lover. May be you admire him part of the body for such person that none in your partner, that is normal. I hope your not beyond what I say it is unfair to your BF... see you around

It is not a normal thing to crush a person though he/she have lover...but if this attraction is came with both side then its may be difficult to ignore...
