>Is there any risk of damaging your erection quality when you expand your urethra?
Absolutely possible to fuck up a ton of stuff doing it. We're talking split hotdog possibility. Generally you'd be dealing with other damage long before that point though if you're being forceful.
>Also: has anyone here used bad dragon/weredog mini dildos to sound? I'd want to do it entirely with those
You mean the teeny weenies? Yep. The knot ones are great.
If you're serious about getting into this shit, take this to heart:
-don't use anything not made to go in the body
-don't use ANYTHING abrasive, period
-use plenty of lube, personally I squirt some down the hole first too but I'm pretty well opened up, might be tough for starting off
-GO SLOW, increase size GRADUALLY
-TAKE BREAKS, and I mean days possibly weeks between sessions when starting out
