It really depends on what you're doing it for. The vast majority in the community are in fact just interested in meeting others having a good time and hopefully meeting the girl that makes their heart do backflips. Others however are just looking for sex and are completely uninterested in finding a relationship.

If you're just looking for sex then you really need to be open and honest about that before the deed. This generally doesn't hurt your chances of getting with people, it just means they know not to get too emotionally involved. Girls like to have fun too! They just need to know beforehand that they shouldn't be letting themselves get attached to this guy that's not looking for anything more.
