Unlike the longer and hardier male version, the female urethra is only a few inches long and kind of fragile. It's a very short trip to the bladder, which really doesn't want you dragging in dirt all over its nice clean floor. So while I generally counsel people, especially beginners, to leave the urethra alone and go play someplace safe, like the vagina, I'm going to take a flyer and suggest the urethra as a slightly safer alternative to the cervix if you absolutely must go poking in places where you're not invited. At least you can sort of resanitize it by peeing afterwards. You may also feel free to be cranked open with a speculum, even a cold speculum for that frisson of gynecological authenticity, and prodded about the cervix with a gloved finger. It is possible — oh, so very possible — to create some quite intensely painful sensations in that region without ever attempting entry. I can't, in good conscience, support your friend playing doctor in the sanctum sanctorum there. I just can't.
