What do ypu mean by presence? If this is a spiritual act I would like to discuss, if it's about you getting attentoin, then yes looks posture, maybe even nofap lol, they help obviously
Wouldn't call it spiritual. Might feel like something spiritual to someone trapped in their mind for years and then suddenly becoming present, like normal people. Many gurus talk about it like it's a superpower, but it's really very mundane.
Presence is not really about getting attention, it's about giving attention. The result of that is often that people notice that you notice them and give attention in return. Maintaining presence is harder for people whose own minds occupies their attention, you're not present if you do not pay attention to and understand what's happening around you at the present moment.
Being present with a woman is critically important. You simply cannot respond like and seem like a normal human being if your mind is stuck in itself. You cannot notice opportunities if your attention doesn't go out to your surroundings. You may even kill yourself by such ignorance, by literally not noticing danger ahead because some stupid thought kept your attention occupied.
Being present isn't just a trick to get attention, it's what makes you notice things and take appropriate action. It's in fact critical to our survival to maintain presence.
