I know guys sometimes have an outpour of emotions almost frantically, but do girls too?

Absolutely. The short and long answer is yes! there is really no difference in how men feel and express emotions, the differences are more individual and stemming from our personal experiences, background, cultures etc.
Sure. We are all human and all humans have emotions. Each person learns to manage emotions in there own way. Some can supress them or channel them. Some let them loose. Excessive outpouring is usually a sign of either a build up explosion (more in guys) or a serious matter (more in girls). When emotion is managed in a healthy way, explosions are less and blood pressure is better.
