Are there any health and safety issues regarding it (besides not getting stuff stuck up it, of course)? Such as, will it bleed if sufficient lube is used, and will there be any complications with passing motion? And how wide is a wide enough base for a plug, assuming i try to make one myself?

Also, kinda off topic, but is it really possible for -anything- to get stuck in your vagina? I really don't see how that can happen, but I've heard stories of a girl pushing a dildo/vibe in too far and it got stuck :/
