My heroine, possibly to her discomfort, is trying to secrete a smallish item inside her vagina. I've searched various combinations of drug mules, concealing contraband and cavity search/intimate body search, but all the links I found were more from the perspective of a law enforcement officer trying to detect such concealment than describing the experience of the smuggler herself.
I'm afraid I have no idea at all how to tag this question. :-) Thanks!
Edit: Thanks for the replies! It looks like:
1. Not very noticeable at all as long as it's far enough inside, but possibly painful if it isn't - and I need to consider the item's temperature on first insertion.
2. It'll stay in place as long as it's not too heavy.
3. Less agreement on this, but there seems to be a consensus that she might be able to push it out with kegels (or have an orgasm!) but is likely to need the assistance of fingers or similar.
