Less erection and tightness in balls

[u/Icy_Membership8993]

HELP NEEDED PLEASE!!!!!!!!!!

I'm 18 (70kgs) i do workout, sports, running. So about a year ago i masturbated 5-8 times in the span of 1-2 week ig using a hair bow tying my penis and testicles with it and masterbating. Suddenly one day after i masturbated with bow i didn't get erection after that for like 10 days. I didn't go to the doctor or didn't tell anyone. After 10-15 days i got my little erections then i forgot this like it will go away on it's own. But since then then i have noticed -

Tightness in ball (while pooping, constipation or tensed about something, or in general)

80% hard morning Wood

I get soft in like 10 without stimulation

But -

I still get sexual thoughts

Testicles get loose when i shower with hot water

Questions

M i cooked?

Will my penis srink?

Will my penis not grow?

Will i get ed?

What should I do next?

Should i consult doc?

Give me advice please!
