Did you know that when you enter a woman womb, in reality, you are inside another human being, that you become one with her?
Do you ever realize how sacred that is? That this is as close to unity as you will ever experience, and that she has that gift for you. Whence you go back into the womb you are born again that you can plant the seeds of creation in her too. That when you leave her, she feels the separation as you physically withdraw and leave her empty.
That being allowed to enter, is a gift, an honor, something sacred, and that it is your job to know, respect and honor this.
That her heart and her sex are yoked, and when you want to enter her sex, you also enter her heart. She feels everything when you enter since all your energy is existence acknowledged within her.
So, you have the responsibility to enter with the transparency of intentions, since she will feel all the ways you could use it to avoid feeling her pain or emotions.
You have to be aware of why you are entering it, and what you are filling it. That sex is the cosmic union of feminine and masculine energy, a sacred meeting of polarities, and it has nothing to do with reaching orgasm, if it will last long enough, size, another number for your collection or your value.
To open up to a woman is to go deep, but not go deep inside her, it is to go deep inside of you, to know yourself. The deeper you can enter you, the deeper you can enter a woman.
