I always thought that a woman was hard wired to wait for sex and be more selective because she is stuck with the consequences (children) for years.

Yet this community explains that if a woman likes you she wont make you wait for sex. Doesnt this conflict with the evolution hard wiring to be selective? I mean if she is fucking a man that might not stick around thats historically a potential death sentance for her children right?

Attempt to answer own question - I guess it might be partly because society and birth control allows them to skip the serious consequences?
