I like a girl,Im a "boy"

At first ,you should make sure whether the "love" you show is true love or not.
As you say that you sit together.As far as I know only in primate school or junior school,boys sit with boys,and girls sit with girls.
If so,you are so young,aren`t you ?
Then,the love you say may be just a kind of excitement.You may put it down for some time.Maybe you will forget it as you grow up.
If not,then you should make sure that whether the girl can recieve homosexuality.If she cannot,be careful,or you may lose your friendship.

hm...
i don't get you
do you expect me to answer your question of telling her or not?
or do you expect me to correct your grammar mistakes?
and also what does "" this mean ?
is it ironic?

你的英文表达不是很好，有语法错误
但是友人说，如果你18岁以前都没有恋爱过，你的人生就不完整。
本人赞同。因为中学的感情是纯纯的没有什么社会的东西进来，上了大学后，走向社会后，味道就变了。那种青涩的感觉你就再也体会不到了。大学里没谈恋爱没人笑话你。如果你18岁以前都没有恋爱过。你将真的在生命里缺少了什么元素，因为时间是不能倒退的，以后你再找也不可能有18岁恋爱的感觉了。
