Love at first sight? No...
Lust at first sight? Most definitely!
Don't you think lust is an important part of any attraction?
Think of a world without it... I doubt very much we would even be here. People simple wouldn't spend any time trying to attract the opposite sex. A sloth race that would have died out due to lack of interest.
Lust is a basic animal drive. It's one of the few remaining animal instincts we still possess at this point. It heavily influences our lifestyle both positively and negatively. The trick is finding a healthy balance.
