Is my personality okay?

Your personality is completely fine. I'm the same way. Girls will see that your personality is great after a while of hanging out with you it just takes time. But in the end all the girls want a guy who's a little mysterious.

Yes! Your personality is fine. Don't change to someone you are not just to be with girl. You want to be happy right? You are not going to be happy when pretending.

Just know, once you're 21+, everything you thought at 18 will be stupid and embarrassing.

Trust me: stay in school, don't get someone pregnant and keep reflecting. Save this post somewhere so that when you open it 3-4 years from now. You'll only be able to read half of it through your fingers because you can't believe you wrote this.

Girls are all sluts except our mothers.

Your personality is fine, you just have to practice your social skills more. Everyone experiences this, a lot of people are shy when they are young and they learn to be more outgoing. Practice talking to girls more and just make friends with them (genuine friendship, don't try to use them. They will tell if you are faking) . This is to get you used to being outgoing and social with new people. You will also make more female friendships that you can ask questions, get advice on dealing with women, and it will help you understand women more. Some of these girls might enjoy playing match maker and hook you up with a friend. Just practice talking to girls and understanding them (think about how you effect people emotionally and how they affect you, a lot of guys don't do this)
