The speaker suggests that attractive women may be especially likely to form friendships with gay men because these friendships can offer trusted, useful feedback.

• Gay male friends may provide honest advice about appearance and dating, without the competitive motives that can arise between women.
• They are also less likely to give misleading reassurance to undermine a potential rival.
• Because the friendship is not driven by an attempt to pursue sex, it may feel safer and more trustworthy to women.

The speaker presents this as an explanation for the perceived bond between attractive women and gay men.
