As you grow up, you leave your parents house. You meet new people in college.
If there is one thing you will learn, either quickly or the hard way. It is that we are all different in one way or the other. Not all the people you will meet share the same value as you do.
This is totally okay. What Is not okay is if you ever decide to compromise your identity and values to please society. This can be through a subtle act, or a bold act.
If this guy you are dating wants you to have sex with him in order for him to make things more serious. My friend that is a big sugar coated lie! If you are one of the handful of girls who wants to wait before jumping that step. Then do not do it. If you decide to have sex, and compromise yourself, things will NEVER be the same again. You will be deciding to lose part of you for someone who is probably not even worth it. It does not matter how long you have known the person and how well he treats you. This is about you and you alone.
If in the group of people you now hangout with. You almost always feel like you have to lie or lose a bit of your personality to be around them. Then my friend it is either you show them who you really are (which I am sure is really amazing ❤ ) or you decide to find yourself new friends who will help you be a better person.
At the end of the day, it is all about your happiness. Pursue it.
