Oh look at those 2 dogs! How lovely, but do you know that animals can't afford to waste energy so most of them have sex solely based on reproduction instincts! Many people have sex as a recreation activity, but at your age that is not appropriate at all!
Oh look they are about to kiss! First love is really romantic but there are always pros and cons in a relationship. Love can be blinding and sometimes we only see the good side in our partners. That is why we need to spend more time to get to know them before we make any intimate moves.
