OK, riddle me this:
A very sweet colleague underwent a hystorectomy because she had cancer. Should she now forgo sex? If so, please provide both scriptural and secular rationale for such a decision.
No, she should not forgo sex. If she's able, she should feel free to make love with her husband.
Scripture: Song (or Canticle) of Solomon, entire.
Secular: (assuming you're talking about marital sex) there's still that good pleasure-bonding thing with her husband.
