You something has annoyed me for some time now.?

Many people, guys and girls alike, tell me that the reason a girl wears as small a bikini as I do or sunbaths topless, which I do on occasion, is to attract guys. I have a problem with that whole scenario. I've been going to the beach on week days this summer. During the week on most days I will lay there the whole afternoon and not see a single guy or anybody else for that matter of fact. Even the Life Guard Stations are closed. Yet I am still told that girls wear a bikini or sunbath topless to attract guys. So now boys and girls what is the real truth there?
