Until a few decades ago it was inconceivable for a woman to kiss a man by her own initiative. However things have changed and the 21st century woman is more on a “If you want it, get it!” motto.
So if you’d like to kiss the guy you are dating, you shouldn’t hesitate. Of course there are certain risks to be taking into account. You might be perceived as aggressive or intimidating but I think it’s a worthy risk. The only thing you should take into consideration is that your will to kiss is shared by the targeted person as well.
