We are sorry that we did not keep a tally of the number of students approached. We have added to the Limitations section of the Discussion about this (see p. 12). It reads, First, the participants in the study were predominantly middle class, Caucasian university students, residing in one region of Australia. There is also the possibility that individuals more interested in sex and relationships chose to participate. Therefore, the results of the current study may have some limited generalizability.
Second, potential participants were "approached at a university campus" during orientation week. What percentage of people who were approached agreed to participate? How broadly representative of the university population (or the university-age population) is the sample? From the relatively high percentage of non-heterosexual participants, there seems to be some selection bias. At the very least, the Discussion should consider how generalizable these results are.
