Couple looking for couple or single woman

We just can't believe that all Stanford students are so conservative, so here's our try:
We are a young couple of Stanford students (he = 30, she = 24 years old). We live together and we have an open relationship. We are interested in meeting other couples or a girl (single) who are interested in topics such as open relationships, multiple partners, etc. We try to be as jealous-free as possible, and develop relationships based on sincerity and simple, clear agreement among all the parts.
Let us know if you are interested in chatting by e-mail, and, if things go well, meeting in the future for a drink or more.
