Sounds like you lack in defensive skills.
Sure, everybody (or everybody who is "normal") prefers White. In the month of July, I've played a total of 11 tournament games over the board thus far. I have 5 wins, no losses, and no draws with White, 3 wins, 2 losses, and 1 draw with Black.
In your case, sounds like you need to read a book on Defense. But even then, one's White results should normally be better than their Black results. Overall at the GM level, White tends to score about 54% while Black scores 46%. Break it down further, and it's usually 56/44 in favor of White after 1.d4, 54/46 in favor of White after 1.e4, and 52/48 in favor of White after a Flank Opening.
If you can score over 45% with Black, you're doing fine. Your expectations should be loftier (i.e. 55%) when you have White.

Hello Everyone,
I Love playing chess but I always prefer playing as white pieces and If I play white more chances that I'll win and with black I don't win so much as compared to white pieces and I feel "uncomfortable" with black pieces. Why is that so? How can I improve my game with black pieces?? any help?
