A little study, after reading (all available free online without research accounts as pdfs):

• International preferences in selecting mates - A study of 37 cultures (1990) - DM Buss
• Sex differences in human mate preferences: Evolutionary hypotheses tested in 37 cultures (1989) - DM Buss
• Global Sex Sexuality and sexual practices around the world (2000) - Judith Mackay

Topics raised (in Buss 1989, and peer responses):

• Orgasm as a gauge
• Partner's likeness to parents
• What do males and females choose based on
• Value of these criteria under different circumstances (eg when women make more money; in an industrial society, children's values)
• Criteria that is most variable across cultures (age, chastity)
• Actual choice versus said preference, actual satisfaction, retrospective judgement
• Authority of the sample
• Rape offender's preferences
• Modification of choice based on thinking (type of relationship, acceptability of relationship to others, thoughts about what is healthy, thoughts about what is simply available)
• Value of coyness and easiness
• Moko dude
• Evidence from deception
• Spain as a possible outlyer
• Women put off more by unfaithful husbands
• Mammal females are hard-working mothers
• Employed women a return to historical economic role
