I don't know why but it is extremely difficult for me to have crush on guys. I mean I have lots of guy friends and I work with lots of males in the company. I personally know a lot of good looking ones and funny ones but I am never interested in any of them.

To me appearances mean little, if I don't get to know the guy I won't have any interest. On the other hand I have no desire to get to know anyone since I don't have crush on anyone.

Am I too logical as a person or I am just a late bloomer? What is wrong with me?

P.S. I am in my early twenties, and last time I have checked that I am a woman.

Nothing's wrong with you. Perhaps you just like being single, it's nothing weird. I know plenty of girls like you.

I actually just recently dated a girl like you (she was 22... and the date we went on was her FIRST DATE EVER... never had a boyfriend... just was never interested in it). There was nothing wrong with her, as she was really pretty, really smart, and just recently was offered a great job at a huge company.

Most likely the right one hasn't come along to catch your 'eye' yet.
Don't worry

You're doing just fine. Make sure you are getting out and having fun anyway.
