It’s somewhat twisted to begin this conversation with the notion that only two things are at stake in every relationship—sex from the woman and money from the man.
This is wholly not true but we cannot also a result of political correctness disregard the fact that this sort of relationship exists.
At the start of most relationships, the people involved are usually not fully certain. The woman who mostly regards herself as going to be at the losing end should the relationship pre-maturely ends would work overtime to protect one important thing from being taken away from her, sex.
During this time, some women would make it clear they are not ready for sex, even if they believe in pre-marital sex. In a whole different conversation, others will boldly say they are not going to have sex until a ring is on the finger.
