Lots of guys come here seeking injury advice.
Often they say they have, for example, hard flaccid, or can’t get a proper erection after doing some PE. Then they ask what’s wrong and what to do about it. Doing that may get you some advice, but you could get much better advice if you give more details.
Only a medical professional can give a diagnosis, and for that they will need to see you.
The best you can hope for here is some good advice from someone who has been through what you are experiencing, and have found what worked for them, or who have other knowledge of your condition. There are doctors here, but they are not going to advertise that fact, nor would a genuine medical professional of any type ever try to diagnose your condition over the web.
So what questions should you answer to get the best advice?
Here are some examples - you would do best to answer them all, but you could pick and choose from the list. Copying and pasting them into your post is a good idea, along with your answers.
Age?
General health (are you fit enough to walk a mile fast, or play a full game of basketball etc. or are you more of a couch surfer, for example)?
Do you take regular exercise? Aerobic or resistance or both?
Under/over/normal weight for height?
Do you smoke? How much?
Do you use other recreational drugs (including alcohol) Much or little/occasional or regular user?
Are you taking any prescribed medication? (Include anything which would be prescribed but that you get elsewhere, e.g. prescription painkillers, ED meds etc.)
Are you taking any over-the-counter medication? (e.g. antihistamines, NSAIDS etc.)
Are you using any dietary supplements?
Do you generally eat a healthy diet, or do you live on fast food and cookies?
Do you suffer from anxiety, stress, fatigue, depression etc.?
Are you typically physically relaxed ot tense?
Do you have any known health conditions (e.g. cardiovascular disease, diabetes, neurological problems, hormonal imbalances, thyroid disorders, asthma etc.)?
What symptoms do you have?
How long have you had them?
Have they been the same over that time or have they got better/worse?
Have they improved for periods of time (e.g. when you are on holiday or doing different work)?
If symptoms have improved or gone away for periods of time, how long did they improve for?
What makes the symptoms better? (think hard about these - anything from less PE/masturbation to drinking more H2O to doing meditation etc. is useful info)
What makes the symptoms worse? (think hard about these - anything from a hard day at work to alcohol or lack of sleep etc. is useful info)
Are there certain times of day the symptoms are better or worse?
Are the symptoms better or worse when you are in certain positions (e.g. sitting, standing, laying prone or supine)?
Have you seen a medical professional with your symptoms?
What type of doctor?
What did they say?
Did you have any tests?
How do you think your condition/symptoms occurred? (Be very honest here, or no-one can really help you, e.g. don’t say you did a few gentle jelqs if you strangled you penis, or that you did a bit of stretching if you stretched as hard as you could, or that you tried clamping if you wore a constricting device all night…)
Is there anything else you can add that may be useful to know about yourself or your condition?
