A while ago, library bathrooms used to be your campus's default hooking up grounds. No one really thought there was anything wrong with this.
This is where you would connect, and quickly move on to a more private environment. A few guys would prefer to hook up at somewhat quieter times, so that some action could take place there and then... This, too, used to be a widely known fact that apparently everybody lived with.
Much of the popularity of such places had to do with the time/money economics of such hook ups.
Most players were there or close by anyway. You did little or nothing of preparing yourself for a hook up. No one felt that they had the whole night to strategize and play sexual politics. You looked around. If you liked someone, you'd let the guy know, and you would move on. Simple, inexpensive, easy and efficient.
So, yeah, if you enjoy it, the environment is relatively safe, go for it
