Conclusion
Lois is another girl who feels quite guilty about having sex, and there is no reason for that. I tried to tell her this again and again, but since she was raised by her aunt, who lives by the sex standards of the old days, she has been taught to think that sex is dirty.
Lois is also a romantic. The media has influenced her into thinking that the swashbuckling pirate days were filled with romance, and that is why she fantasizes about that time. Also, the fact that the pirates forced their woman to submit against their will helps, too. It justifies the sex in Lois's mind.
I don't think that there's anything wrong with her, however. Many women have these fantasies. I told Lois that although she didn't like sex with Mark, she also didn't confess and tell him what she really wanted. Mark sounds like a reasonable young man, and I'm sure that he would be willing to play the forceful pirate to Lois's maiden in distress. He already has the costume for it.
