Hello there modern Man. Do you know that you have four different type of erection, not just one, four. And Mother Nature program you to have it that way. All right. I'm Dr. Anne Truong. I've treated over 7,000 men with ED over 20 year span. Let me say it again, you heard it right. There are four different type of erection that you can have and they're all erection but they are kind of created a little differently. But your body is programmed to have erection kind of like the same way that why you need to have sex, because that's the way your body is programmed. Let me start with the first erection, that is the morning erection. And you've had that probably since you're an adolescent, right? When you start making testosterone and puberty and morning erection usually happen at nighttime actually. And you can have between three to six erections at night with the most prominent one in the morning when you wake up. However, it only happens when you're in a dream life state called rapid eye movement. And that is spontaneous. So it happens when you are asleep because that's when you're in deep sleep, you're dreaming and you, and you're in a parasympathetic state. And when you're in a parasympathetic state, the nerve is stimulated, you're releasing nitric oxide, you're increasing blood flow, therefore erection. So that erection number one is morning erection or even nighttime erection. You get about 3 to 6 of that in a night. How good is that? Right? Number two is cough spontaneous reflux erection. Now this erection involves touching, right? Any type of touching any of the erogenous zone or touching on the penis itself. You know that you have more than 30 erogenous zone in your body and with 12 of it just in around the penile area. So touching, so it's a reflex. So if you touch and then it sense, then there sense sensation to the nerve in the spinal cord, it goes in a loop like this. Sometimes it can even occur with just the slightest touch or even just wind blowing near your penis. That's Called reflux. So it goes to the spinal cord, the nerve at S2 and S4 and that causes that reflux. Erection sometimes kind of happen at embarrassing moment, right? Or sometimes kind of happen, you're brushing against somebody and whoa, there goes your erection. Sometimes you can't even control it. So the younger you are, you may notice that you can't control it as much. Men struggling to stay hard. Most of the time it comes down to poor blood flow. That's why I put together the Good Morning Wood Smoothie, a nutrient packed blend designed to restore blood flow naturally. My patient often notice improvement in just a few weeks when they take this part of their daily routine. Click the link below to get the recipe and start boosting your blood flow and firmness today. Or go to good morningwoodsmoothie.com Number three is psychogenic erection, where you get an erection just thinking about it. You get an erection when you, let's say, close your eyes and you think about it or even when you're reading erotic books. It comes from your brain. Then your brain releases hormones and release neurochemical, which then sends messages to the nerve at the base of your neck, which sends messages to the parasympathetic nerve, which then open up blood vessels, releases nitric oxide, which then increases blood flow and therefore you get an erection. Now that is something that sometimes you do without even thinking about it. That's when you're kind of dreaming or when you close your eyes. Sometimes that will happen and just know that there is a large psychogenic component to getting that erection. So then the fourth one is the most common one where you get an erection during sexual arousal, which is a combination of both psychogenic and also the reflex erection. That means that the combination of both pathways of the brain would then send messages down to the penis and then also the reflux pathway where it involves touching. Now imagine two pathways merging to give you a full on erection. And that's what you get during sexual arousal. So sexual arousal involves touching and using the five senses in the taste, the smell, the visual stimuli, the audio stimuli and touch to combine with the psychological component of being aroused, being in the mood, being present with yourself and with your partner, being intentional and not overthinking it. So that's why sometime during sexual activity, if you're worried about performance and you had anxiety or depression or being distracted, you may not get an erection because you're distracting the pathway that is generating that erection. Okay, modern man, if you're struggling with weak erection, low energy, the food you eat could could be the big part of the problem. One of the best research back ways to boost circulation, support healthy testosterone and improve sexual performance is the Mediterranean diet. It's packed with food that open up your blood vessel, lower inflammation and fuel your hormone naturally. I've seen men notice real improvement in both energy and erection within weeks when they shift to this style of eating. So check out the Mediterranean diet link right here below and get that as soon as you can. Stronger testosterone and better erection. So overall, there are four different type of erection that you can have. How interesting is that? So let's summarize. The first is morning erection or nighttime erection, which happen when you're asleep, is the mother nature's way of exercising your penis for you. And that you should be able to have it, which is a good sign that you're having it and you should continue to have it. And one way to optimize it is to have good night's sleep and relax before you go to bed. The second type of erection is called the reflux, which is through touching or through pressure or touching the erogenous zone, which then sends messages to the nerve in the spinal cord which send a message to create an erection. That's the reflex. Number three is psychogenic or mental, which you can send messages from the brain, which then sends signal down to the penis for an erection. And the fourth is the most common one during sexual arousal is the combination of both psychogenic and reflex or touching, which is the most powerful of all. So knowing that guys, you just need to remember to be present, be aroused, be aware, don't overthink it. When you overthink it, you're going to talk yourself. Your erection oftentimes just go with the flow, go with what's going on, enjoy the moment. Oftentimes you're enjoying the moment, you're not thinking about what the what if or what's going to happen. So four different type of erection. Optimize it, relax and overall, guys, it's all about the four pillars of maintaining your sexual health. It is following the Mediterranean diet, exercise, 30 minutes, three to five times a week. If you can get a good night's sleep and decrease your stress. How do you decrease your stress? Through exercise, through stopping the screen before you go to bed, through socializing with your family and being present for your partner. Those are simple things that will go a long ways. Research has shown that diet, exercise alone work even better than Viagra. Because if you're taking that medicine, Viagra in your body, you're going to screw up the Whole entire natural process is how your body produce an erection. Remember the last episode I talked about mother Nature's way of wanting for you to have an erection, taking care of you and and optimizing you to have an erection. Don't ruin it, okay? Continue that process. Nurture your body. Take care of your body. It will take care of you. Take care of your body, take care of your heart and that will take care of your sex life as well.
