Over trained or injury

Hi, I’m new to the forums, but have been doing the newbie routine for 4 weeks now. I started with stretches for 5 minutes and jelqs for 10 minutes. I gradually increased my jelqs by 4 minutes each week. Yesterday I jelqed for 22 minutes. After jelqing, I got an erection and measured it, but did not masturbate. Later that day when I tried getting an erection again, I could only get a half mast erection and ended ejaculating as soon as I got it without even stimulating myself. At night when I went to bed, I couldn’t help ,but think a bout sex, and it gave me an erection that was half mast again, I then ejaculated prematurely. I want to make it clear that I did not masturbate last night. I ended up ejaculating prematurely every time I tried to get an erection, without even touching my penis. I am in no pain, but do have a smaller flaccid and my testicles are riding up as if I were cold, maybe cause I’m tense. I’ve always warmed up and warmed down before and after a workout. I haven’t tried getting an erection today, I plan on resting for a few weeks. I’m 24 years old, and did notice an increase in length at week 2. Not having a full erection and ejaculating prematurely as soon as I got an erection really scared me. Have I over trained or injured myself? What do you guys think?

Yeah, rest. Your dick is avoiding a full erection and is shrivelling up cause you at least overdid it. It wants to get it near to the body to give it healing.
No pain and no numbness is good. Just rest and dont masturbate for some days. Keep it warm and eat healthy(no alcohol etc.).
Relax. In simialr cases it took sometimes some days and up to two weeks.
Start only slowly back to your routine as if you would start all over again.

IF it goes worse, or no improvement after days, you have to see the doc.

Thanks,dickerschwanz. I appreciate you taking the time to reply. I guess I overworked. I’m gonna take 2 weeks to a month off.
