I want my dick to be small
 

Any suggestions on how I can get my dick small I'm a 52 year old male that's been castrated but been on testosterone until today I stopped my injections hoping this will stop my erections and make my dick shrink

There's a story here you aren't telling us.

If you are castrated and you stop taking 'T', then your erections will stop and, lacking the exercise, your dick will shrink.

I'm with smallballs - what's the backstory here?
