It depends. Being in a relationship, when my boyfriend visits (or I visit him) we have sex upto four times a day, but another girl on my floor has told me she only has it about once a weekend with her boyfriend. Hmm, so it varies from couple to couple. And the singletons don't seem to have as much sex as expected. Most people just aren't really looking or only seem to have got laid like twice since Uni's started.
