Easy there, Gloria Steinem. Let's not generalize, mmkay?

Yes, the male ego can be delicate. Don't ask me why; it's just the way we are built. Guys are competitive, with each other and often with the opposite sex, too. And that's a shame, because males and females are built to be perfectly complementary to each other. Our qualities enhance your qualities and vice versa. Your yin to our yang. Our chocolate in your peanut butter. Your magnet, our steel. Capiche?

I learned a while back not to compete with women because every time I did -- with my sisters, my female friends, my wife -- I lost. If there were such a thing as a weaker sex -- and I have my doubts -- it's men, not women. No, I'm not just saying that because this is a women's site. I say it because my wife is reading this answer.

On the other hand, your question makes me think you might have a chip on your shoulder, that maybe you think you are smarter and funnier than not only your boyfriend, but every man on the planet. Which, of course, you are not. So your eroding relationship might be more about you than your man. Just saying...

Bottom line: some guys are threatened by women, some aren't. Some women think they are smarter than men, some don't. Sometimes women are smarter, sometimes men are. The older I get, the more I realize that life has very few black and white areas, but lots of grays, and that generalizations rarely hold true.

If your man is competitive with you, I'm guessing that's just one of several problem areas in your relationship, and that you are both probably equally to blame. As always, it's best to tend to your own back yard before you complain about your neighbor's.

Good luck.
