The average women you date don t just want your money or presents. Girls have the mindset that sex is giving something away. The less you give out, the more valuable you are as a partner.
To be given a token of trust and value, a girl will feel more comfortable and valued and feeling valued is so important with intimacy.
(I m not saying that in all cases, just in general)
However, if you think women want your money, you will only attract girls who want your money! the good girls will scatter quickly, feeling disrespected and violated.
