For a girl to date you, she needs to trust you.
For a woman to have sex with you, she needs to trust you as well.
And you don’t build trust in a relationship later. No. You develop trust from the start.
And if you want to build trust, even if you know nothing about attracting a woman, you need to avoid giving her the wrong vibes and turning her off.
Think of the interaction from a woman’s point of view.
