Dating question: Confused!!?

So, Hey, I am a really nice guy. I like people, I love people, I live for people. I never really had the oppurtunity to date when I was younger. I'm 23 now in school. Surrounded by women and men. I consider them all friends. I know a lot of girls like me. But I try not to pay attention to that when they are talking to me. I guess thats why they like me, because I am not interested in using anyone and im just genuine. So how do I go about this. I want to start dating, I want to start exploring. I dont want to overthink about it (trust me I could) So I find a girl, I appreciate and ask her out. Does that change anything? What am I getting myself into? I mean we dont have common groups of friends that hang out together. I can try studying with them. What if I meet someone I like even more? Is'nt that the point of exploring? I am confused..
