The decision to have sex is a personal once. Unfortunately, in a dating relationship, there are two people involved who both feel very personally (and often very differently) about the subject. If the person you are dating pressures you to have sex -- and does not respect your right to say 'no,' this is one of the biggest red flags you can get. If you are uncomfortable with your date's advances, tell him/her. Their response will reveal their true feelings about you. If they continue to pressure you, they aren't listening to you; they are disregarding your beliefs and values; and they are not the right for you.
