"He/She was saying NO, but I could tell that he/she really wanted me to go on."

No means exactly what it says. NO! When you don't listen to no, that's rape. If you hear yes when he/she says no, you are only listening to the sound of your own voice. Also, remember that sometimes people don't
always say no directly. If there is the slightest doubt, ask.

"If you really love me, you will do it"

If you really love the person you are with, you would not ask something of them that you know makes them feel uncomfortable. There are many ways to show a person you care for him or her. Guilt trips and high-pressure tactics are no way to show someone you care about them.
