I don't think it is just boys who are more leery of girls, but men also more leery of women. I know a number of very nice guys who abstain from even trying to have reationships with women beyond casual co-worker comaraderie. Women apparently feel safe in being forward and making critical comments about males, but for men this is more risky. They have been well-drilled on the dangers of sexual harassment and sexual discrimination -- it can cost a man both legally and financially. And, from what I have seen, women are more free to openly talk and laugh about sexual matters, including a review (with other women) of the man's sexual abilities or lack thereof. I have overheard conversations between women that included descriptions of their date's penis (positive and negative), with much laughter at what would be great embarassment for the male. Men I have spoken to don't go into as much detail . . I don't think they want to paint that picture of their date's body for me . . and do so more in whispers or behind a closed door with one other person (man). Funny how the traditional images were of swaggering, boastful men, and the discreet, delicate and easily embarassed women. Now the roles appear to have reversed, at least in my experience.
