Tell that person you are not ready. If they tried to get forceful then that is considered rape. No means no.
Dr. Susan: Sex should NEVER be something you do when you feel pressured. It is something you get to decide to do when YOU want to, not when someone else thinks you should. It’s your right. Besides, women especially require feeling relaxed and comfortable in order to have a healthy sexual response. If you feel pressured, rushed, or threatened, you are more likely to have tense muscles and dry vaginal tissues. This increased the risk of pain during sex both for you and your partner. Let him know that you’ll tell him when you’re ready (and that you may never be ready), so stop asking. You’ll be more ready when the relationship is balanced, equal, and based on both of you really caring about each other. If he’s only hanging around waiting for you to change your mind and say yes, then maybe he should find someone else.
