I think you may have just made my point, especially since you've pointed out that women may not see a man as a potential sexual partner until further into the relationship when a connection has been established.

Men being so worried about being put in the "friend zone" are potentially missing out on great partners because they are unwilling to actually form connections with women with no expectation of a sexual relationship.

In effect you are attempting to shortcut the process by jumping straight to sexual attraction and expecting that a woman will know whether she wants to have sex with you based solely on appearance.

Most women don't operate this way, which means most men will get declined when they attempt to figure out whether a woman wants to have sex with him straight out of the gate. Then, men are stuck in relationships with women who maybe initially found them attractive enough to have sex with, but had no other connection apart from that.
