You should never do something that makes you feel uncomfortable. It's normal for men and women to want "action" but if your partner truly cares about you than he or she will not pressure you to do anything beyond your comfort zone. When you become physically intimate with someone you should feel great and amazing, not queasy. So if your not feeling the passion than move on, but don't every force yourself to do anything you don't like, especially to please someone else.

Give it time Toluca, you'll eventually find someone who makes your heart race and skip a beat. And don't let that "non-relationship" scare you. You should never carry your mistakes, instead you should learn from them so that you can become stronger. In the meantime just have fun with life, you only get one shot at it.
