Leave before the lights come on.

I remember when I entered high school my mother started to have "the talks" with me. She wouldn't bore me with the details of what had to happen for conception to take place. It was more like "I know that in this day and age it is impossible to wait till you're married and I don't expect you to but I would like you to wait until it's with someone you love. You see, after a woman has sex all of these hormones are released that makes the woman feel attached to the man and very emotional towards him. This is why women love to cuddle and have deep conversations after sex. Men do not feel this way. Men want to sleep. So make sure you pick the right man to have sex with that cares about you."

All of these talks with my mother didn't have the effect on me that she hoped for. Instead of thinking "That makes sense. I'll wait until I am dating someone and feel like I can really trust and love him", I reprogrammed my vagina, brain and heart to function separately. I told myself that I would not become attached to anyone I had sex with. That I wouldn't do the whole "spooning" thing. That I could fuck and leave like a guy. Guess what. I can.
