I am having a hard time with this. Can you help me?

I am a senior in college and never had a boyfriend, been on a date, or been kissed. I'm not a partier so college hasn't been the best place for me to meet guys. I do go to church, talk to people in my classes, and get involved. Although, through these activites hardly any guys show up and I can't even meet guys in these ways. After I graduate I plan on going to graduate school, and I feel like at this rate I won't meet anyone there either. Why aren't guys interested in me? What can I do? I have so much to offer! Do guys even approach girls anymore? I'm overly worried and just feel so weird for being so inexperienced at my age .... I ask my parents for advice but they don't even know what to do.
