If you feel that way, you don't understand what attraction is about.

Women want sex. They want it as much as men want it. They just don't want to have it with people whom they find unattractive. No shit. Are you any different?

Now, you might say, "but I'm not so unattractive". You might even be Brad Pitt himself, or whomever passes as the male archetype for attractiveness these days, IDK, it's not a scorecard I keep up on. But that's moot. You don't get to define what attractiveness means to anyone. Just because they didn't have sex with you doesn't mean they don't want to have sex.
