boy problems.

So my year has been crazy. I got dumped after being in a relationship for 2 1/2 years. I had some random hookups (I am 21). I developed a crush on a guy and things didn't work out. This was 2 months ago.  And now this new guy has a crush on me and I don't have feeling like that for him. I have tried. I also don't have any sexual desire. Is there something wrong with me?
