Supposedly, according to "Men are from Mars, Women are from Venus", we men like to solve problems. (In the book they tell you to try commiserating instead of attempting to solve.)

It's enough of an explanation for me. I've asked several questions and any time I can help someone out, I try to.

Since Meta won't let me add a comment in reply to the commnents, I'll update here: 

No, I don't think only men answer questions. Nor do I think that the book I reference above is necessarily a good or bad book - it's just something I heard about.
