I have a girlfriend, and I had to work my ass off to get one. Tulane has one might call a "hook-up culture." People go out to bars, get drunk, kiss people they don't know, occasionally bring them back, and then usually not much happens after that. It's a great way to meet people (and stroke one's own ego) but it isn't a great system for finding true love. That isn't to say there aren't relationships. Not a day will go by without seeing two love birds holding hands walking or cuddling in the library. Relationships are a natural part of college and if one really puts themselves out there, they'll happen. The key is that you shouldn't expect a boyfriend or girlfriend to fall into your lap. Even a handsome, charming catch like myself had to work real hard, and meet lots of people before finding one that clicked. A lot of it might have been due to my California style which never clicked with the heavy-set east-coast attitude. Ultimately, there are enough pretty, sexy people that you should be able to get exactly what you want, given you're willing to spend the effort.
The simple answer is that the dating scene is whatever you make it. There is an interesting "hookup culture" at Tulane, as with any college though. Weekends, for many students, consist of going out to clubs with the sole purpose of finding someone to bring back to their dorms. This is obviously not for everyone though, and it is really up to you. If you choose to make this an integral part of your weekends and relationships with people, you won't be judged and you'll make friends with people who have similar ideas. If you want to go on dates more conservatively though, there are those who share that belief as well. You can go to Audubon Park across the street to just have a chat or go to any of the restaurants around the city. Everything is just a streetcar ride away.
I'm probably the worst person to answer this question because I've been in a relationship with my boyfriend since we graduated high school (we were in the same area and went to Tulane together =] ). However, from what I see, I don't think it's too bad. There are a lot of people on campus in relationships. I even think there is a speed dating event at the beginning of the year, but don't quote me on that! I think that as you go out and meet people, you will find someone who is "datable." =] Just don't be afraid to make conversation!
There are your typical random hook ups that happen every week, but occasionally people start to date. I had one friend who started dating someone after the first month of freshman year, and they are still together. Majority of my friends didn't start to date until this year. Also, your grade doesn't really matter when dating. Many sophomore girls dated freshman boys last year. It is easy to meet upperclassmen through Frat parties, date parties that sororities have, at a bar, or even in class (shocking I know).
The dating scene has been entirely redefined over the past several years. Like most schools, Tulane has thrown monogamy out the window and is run entirely by the hookup culture. One night stands are common while finding a partner(s) to have casual sex with is even more common. There are a handful of couples within the student body.Generally these relationships form freshmen year and deteriorate by the spring semester. Because alcohol flows so readily, it contributes heavily to the hook up mentality. Most people meet at bars off campus such as The Palms, The Boot, Bruno's or Rocko's.
