I would say first of all you are spending time around shallow, awful women. All college age women aren't like those you described. There are many young women on every campus who are not as you described. I spend everyday on one as a Student.
If you want to meet girls who might be interested in you, I would suggest checking out the independent non Greek student activities, usually via clubs. You would be quite surprised the number of girls involved in sports, nerd, and gamer culture on most campuses. I (female) am in an off campus dungeons and dragons quest. We have more women than men currently. In a more relaxed social atmosphere, you might meet a really nice girl who likes you back. She might or might not look like a Barbie doll. But frankly the sameness of the dull attractiveness sorority and frat members is boring after awhile.
Also you seem preoccupied with sex. I am older than you. Looking back at all the freaking out of my fellow students over hookups is pretty stupid. And yes, that has been happening for a long time. Hookups can get you only a few things:1. Unwanted pregnancies 2. STDs 3. Serious psychological repercussions
I fell in love with a wonderful, intelligent woman who had cerebral palsy. I loved her and wanted to spend the rest of my life with her. The extent of our sex life was not a concern.
In the grand scheme of life and love, sex is only a part. You might think about limiting the porn because it seems to be giving you a warped view of sex and women.
