Well.....thats not really your tamagotchis fault, know is it? Its your choice on what they grow up to look like. With different care you get different charcters. If you want a cute mimitchi that can look like a boy or a girl, take really good care of your tama. The tamagotchis you get when they weigh 99 pounds and are spoiled usually look like boys. So keep trying different methods until you get the charcter you want.
