You're learning to put logic and reason before your emotions. You even have second thoughts about hitting on your boyfriend's dad. The afterglow of a big weekend last only until the ecstasy runs out. You favour small groups over one on one interaction. Romance and creativity go hand in hand.
Respect is an important element of any relationship.
That includes respect for your body, lard arse. A marathon of intimacy is what you need. A marathon of sex is what you crave. Vigorous physical activity is recommended. Do your best to imitate a well oiled sex machine.
