Sparkly – you have said that you started college early, which means you could not have been more than 17 when you started. I think that you also said that you are in your third year of college, which would make you no more than 19. Even if you are in your fourth year of college, you can’t be more than 20. In any case, you are definitely younger than 25, so you are way too young for dating sites.
Dating sites can be very dangerous. You have no idea who the guys are. It is very different from having someone set you up who knows both you and the guy. In Eretz Yisrael, people meet in hotel lobbies, so dating is safe, because if the guy turns out to be nuts, you can just leave, get on a bus and go home. In the U.S, the guy picks you up in a car, so you have to be very careful who you go out with. If you think about, you are getting into a car with a strange guy! That is nuts!
One major difference between having a live person set you up and a dating site is that when someone sets you up, the guy has someone he has to answer to, and when there is no shadchan or at least not a live one, he has no one he has to answer to. It’s kind of like the difference between taking a taxi that belongs to a company vs. a private taxi driver.
I don’t think you are ready to date yet at all, but if you do, you should start with shadchanim and/or having friends/acquaintances set you up. Dating sites only make sense for someone who has been dating for a few years.
