I’m a male member.

I’m Kazu, a male member. I’d heard that some people remain aroused for more than four hours, but I guess it really does happen. When I first received ICI therapy, the doctor told me to contact them if it didn’t subside within four hours. I also remember being told not to inject it on consecutive days and to leave at least one day in between. At the clinic I went to, they gave me a syringe and instructions and told me to take them home and inject myself. As I mentioned above, they told me to contact them if it lasted more than four hours, so I remember trying it during the day so I could reach them if it didn’t subside. That was over five years ago, so I don’t remember the details very clearly, but I was amazed at how firm it was, and I recall that it mostly subsided after I ejaculated normally. After writing this in the question box—https://universe-club.jp/help/questions/view/4434—I remembered it and obtained the medication, then injected myself three times. The first time, I hadn’t done it in a while and missed with the injection. Since the medication was injected too shallowly, it didn’t work properly. The second time, I used about 60% of the dose, and it lasted around two hours. While I was doing various things before sex, the medication naturally wore off and the full erection subsided. The third time, I used the full dose, and it lasted about four hours. The full dose made me uncomfortably erect, so in the end I masturbated and ejaculated, after which it subsided. There seem to be two or three types of medication, and apparently the formula differs depending on the doctor’s professional lineage or faction. The biggest difficulty with this method is timing the injection yourself. In my case, after meeting a woman, I quickly inject it in the bathroom when I take a shower. Whenever I mention the injection, women say they would have liked to watch me do it, so I’m thinking I might try injecting it while a woman is watching sometime.
