Being sexually direct and honest with a woman we are attracted to.
Let's see:
Most men, when sexually attracted to a woman, usually try to hide that interest for fear of rejection. They even often try to act in an indirect and careful way.
But women have enough intuition to perceive when a man is attracted to them, even if we try to hide it. So all those indirect little games only show her the cowardice of her suitors.
Few men have the courage to approach the girl they are sexually attracted to and sensually whisper in her ear:
"I have X sexual fantasy with you and I would like to know if you can fulfill it."
They don't even do it on dates. Just thinking about it makes their legs tremble, due to the terrible fear of rejection. So they prefer to be indirect and manipulative.
However, women have a very good feeling about all those guys playing their little games and they know full well that they just want a lay, but they don't have the balls to tell them. Even if those are not your intentions, they will still figure it out.
Really most women appreciate honesty, courage and decision. And if you had the guts to be honest and direct, to sensually talk to her ear of her about your true intentions, you might even bring her to orgasm before she gets into bed.
Yes, yes, I know that many are not prepared for this conversation...
I've read some critical comments and am editing this answer to clarify a couple of things:
Be honest and sexually direct about your intentions obviously with women you trust and feel comfortable with your presence.
If you don't feel sure about it, you will always have the wild card of asking him: Can I be totally honest about my intentions with you?
Being sexually direct and honest doesn't mean you're going to tell that girl you want as a girlfriend that you want to have sex with her. Since the reality is that you want a relationship. That's what it's all about, showing your true intentions.
Being honest you will not have more rejections than if you are indirect. The person who is going to reject you will do so immediately or in three years when you finally make up your mind. Being direct will save you time with women who aren't interested in you, and it will save them time as well.
An honest and confident man is more attractive, as a user has said in the comments, since he exhibits great self-confidence. Another important point is that a man like this stands out from most men, since almost all of them are indirect.
Don't do this at your workplace. In general, I would not recommend trying to establish any sexual or loving relationship with a co-worker. First, they can interpret it as harassment, second, in the face of a fight it is very uncomfortable to see each other's faces every day. Unless they are both very mature people, that is.
When a woman tells you no, don't insist, she respects her decision and goes for another. The idea of being honest is not to persuade or induce a response.
