Abstinence is a personal choice.
Whether or not you choose to engage in sexual activities is your decision, and you should never be pressured into making a choice that you are not comfortable with. You must decide for yourself what level of intimacy you are comfortable with, ranging from kissing, to holding and touching one another to sexual intercourse. You have control over your sexuality, so you have every right to decide what is best for you. You can express how you feel about someone in so many ways other than having sex. If someone is pressuring you to compromise what you feel, maybe you should reevaluate your relationship.
