I'm probably going to ask something silly, but the consequences aren't funny at all. We don't live by our sexual life because we're afraid that something will go wrong. This morning I woke up from an orgasm feeling. Seriously. How will I control my desires in my dreams? While lying down, my stomach feels like it's pulling, maybe it's pain and I'm horrified. Could this be due to the morning experience? Can these sensations harm the child? Or is it normal sometimes?
