Bangladesh - Co-Education & Single Gender Education a invisible problem

Hi,
This is my first blog & there will be some mistakes & it will be may be out of topic.

Co-education in Bangladesh is one of the most confusing problems that is faced by most of the parents when they think about their child's school.
Most of them thinks that if they select a co-ed school for their child then in future their child's character will be spoiled by communicating with opposite gender students.That is one of the most wrong things i think. It's normal to have friends of opposite sex.It makes everything normal.
For example students who studies in boy school are way more crazy for girls than co-ed boys.
Students of boys school thinks that it's important to have physical contact with them & they will do anything for it.They collect mobile numbers of girls to call them,in crowded place they try to touch girls & in many ways.They always think that they should have a girlfriend.Not a friend who is a girl but a GIRL FRIEND.On the other hand students who studied in girl's school are as much crazy as the students in boys school.But due to social barrier they cant express it like the boys.But they love to chat over the phone ,like to have a BOY FRIEND while not knowing that if it is the right guy or nor or whether he will use her for his own satisfaction or not.These boys & girls are making wrong decisions because they feel a unavoidable attractions to the other sex because usually they cant communicate with them.Its not natural i think.I am not saying in co-ed institutions its not happening.It is happening but at a very low rate.
If the society will become more open minded then I think we will be able to avoid this problem.
Co-ed won't do any harm.
It will only do good.
