I often rent a luxury car for dating. Many girls slept with me on the first day they met me and kept calling me brother. Is that so?

These girls are very ignorant girls. They are very materialistic. They always want to find a rich husband and live a rich life. There is nothing wrong with this, but it is too casual to go to bed after knowing each other for one day. Therefore, both of you should not make friends so irresponsibly, hurting and deceiving each other's feelings, and at the same time leaving hidden dangers for each other's health.
