Yeterday a female friend in my class who is 30 years old was telling me how she misses her husband a lot because he is away on business.
She then went on to say that she's, "glad they've been married so long, because she no longer feels pressured to have to have sex with him - they have sex maybe once or twice a year, and that's more than enough for her".
I had to hold back my reply of, "so, you're basically friends who live together?"
