How likely is biological problem at age 25?

[UselessMeat]

As the title says, how likely is it that I have a biological problem at age 25? I never tried to have sex before 6 months ago (and I did PMO often before) and I've been rebooting for 105 days. I did about 50 days of hard mode no PMO and have had sex probably 10-15 times in the last 55 days. I am really happy that I am able to successfully have sex (sometimes) but I am really unsatisfied that it is like playing Russian roulette -- I never know when my penis will be dead or not. It seems that I go through periods of my penis working followed by periods of my penis not working -- these periods each last for at least several days usually. Sometimes my penis works very well.. rock hard erections.. and sometimes it just works "okay" (i.e. able to have successful sex but sort of difficult to keep an erection) and other times it doesn't work at all.

I haven't been to a doctor for a few reasons. Firstly, I am afraid that if I go I will hear the bullshit "it's all in your head" when I know it's not all in my fucking head. Secondly, don't have health insurance so it could be very expensive for me to go to the doctor. Thirdly, I don't want them to just throw stupid ED pills at me like viagra. I don't consider pills a solution to the problem. I don't want to have to plan sex and the price of these pills is ridiculous.

I am a little bit scared when I read that diabetes is a major cause of ED. I think I have ONE of the symptoms -- frequent urination. I often have to pee a lot if I drink several cups of liquid, especially if I do this in the morning or am sedentary for a long period of time after doing so. When this happens my pee can be almost as clear as water. However, I've had this for as long as I can remember and I even went to the doctor about this and they did a urine test and they said everything was fine. I have none of the other symptoms of diabetes (other than ED, of course). I am not over weight; I am 6'1 and about 150 pounds (this is in fact, underweight). I eat healthy diet consisting of lots of meat, fruits, vegetables, ginger, garlic, etc..

The other biological problem I am slightly worried about is low testosterone. I guess I am worried about this because I am underweight and because of ED. However, the fact that I have a lot of body hair, thinning hair on my head, and a relatively deep voice makes me feel that low T is not likely.

How likely is it that I have a biological problem? Today I am severely depressed after two failures in a row to have sex. I thought I was getting better and I had a lot of confidence, especially the second time because my penis seemed to be working that day...

I am only 25.. I cannot accept this...

If you were able to get an erection routinely with porn then the problem is porn induced and not health related. A porn video will not relieve diabetes or other health problems.

The other biological problem I am slightly worried about is low testosterone.

Testosterone levels need to be extremely low for ED to manifest. Considering your age, good diet, and low bodyfat, it's very unlikely you have any kind of low testosterone.

I can always get an erection if I start stroking my cock, especially to porn. Depending on unknown factors, my erection will be good and stay strong easily or die easily. I don't understand...

My trouble was getting a boner during sex. I attribute this to a porn lifestyle that hijacked my brain and also general anxiety which made it difficult to cum when I was younger and then difficult to get an erection as I got older. It is entirely possible that a lot of my anxiety about sex is due to the fact that I was under the influence of years and years of porn as well as porn substitutes like hook up apps, scrolling for pics on tumblr, facebook etc.

What I gather from your post is that anxiety might be something you need to deal with. Clearly you are worried about your performance and whether your dick will work or not--which of course starts everything out on an anxious note when you drop your pants.

I have managed to defeat anxiety by 1) stopping all porn bullshit and porn substitutes 2) no longer masturbating ever and 3) waiting fairly lengthy periods between sex--5-10 days. So by the time I do have sex, I'm a little crazy horny and the anxiety takes a backseat to everything.
I also use a small amount of Cialis on most occasions, but I understand that you don't want to do that.

Other people deal with anxiety through meditation, the gym, xanax, etc.

So, in short. I think you are doing great. You are having sex, but you just want it to be more reliable and consistent. It sounds like you are doing a good job on the porn side of things--consider educating yourself about the anxiety part of all this. Being anxious, I suppose, can be called biological, but there are ways to combat it and you should give that a try.
