When young and the awareness of the opposite sex develops powerful desires are felt and lets face it, we are born to breed and desire very hard to resist.  Society has rules, rights and wrongs,  which often dampen the spirit as desires emerge.

When you feel that attraction to another?  The honest thing to do is be as clear about those feelings as you can, then conspire to hang out, spend time with the other and find out if the feelings are mutual,  if it is mutual, then ok, just play, don't make any mistakes in pregnancy or STD's.

Love itself will grow naturally and together you can both design a way of living that is mutually beneficial.

Of course crushes can develop at any time of life, and there is no limit to how many we can have.
