Help! I have erection problems!!

It doesn't seem to want to go down and it’s very embarrassing…

What can I do???

what are u 12 years old just hitting puberty?

well heres what i do, i think of disgusting stuff.

example:
think of someone sticking a needle in your penis hole.(i actually saw a video of someone doing this!! scared for life!!)
think of someone cutting your penis off with a chain saw.
think of someone sticking a SCREW in your penis, and doing it back and forth.
think of someone kickin ur nuts.
think of fucking an ugly ass girl with a disgusting pussy.
think as if u had blisters on ur penis and someone popping them with a needle pin.
think of fucking a metal machine with sharp objects inside, while its ON.

thinking of all these negative thoughts will surely make it go small again. always works for me.
