Is it normal that i believe a sense of humor is overrated?

I have Asperger’s and don’t see the point of having to be funny because I take myself very seriously since I used to make a lot of social mistakes. I’m also not lighthearted or playful and don’t see the point of loosening up.

At the same time, I’ve never had a girlfriend and I’m 25 because it appears that all girls want a guy who can make them laugh but I’m not a comedian. What am I supposed to do to find a girlfriend if I’m not funny?
