Should I consider online dating?

I'm going to be 21 and attend a large university. I have quite a few mates and even though I don't want to count them as dates, I have gone out with some men on one-time dates (maybe like 3). (And these are blokes I'm not necessarily interested in.) I just can't seem to snag someone even though I'm told I'm attractive, smart and funny. I'm just so frustrated because even some of my friends who are a bit less social..and more awkward than myself have significant others. Even my mom mentioned online dating because I need someone more mature.
