Ok, one more dumb thing to ask, but its for a teens' health.?

Alrighty, A doc can tell if you've had sex or use a vibraiter(sorry bad spelling) But can something like a finger break the small wall of skin in the vagina?
Like I;ve said before, I haven't had sex. But in my one Girls Life Magazine 2 years ago, they said I could put my finger up "there" and know that I can't lose a tampan in me, lol.
But when I started useing tampons I started to use my finger after my period to check and see if nothing that might of fallen off a tampon was left behind.
Or could the tampon itself break the skinwall?

The tampon would break the hymen (the skin) so would a finger

All that makes no difference if you have not had sex you are still a virgin.
Yes, not only can those things break a hymen, the membrane that you are talking about, but sometimes just plain vigorous physical activity can do it. Doctor's know this, so don't sweat it. Anyway, it is not the doctor's job to judge you and they must, under law, keep confidentiality. Relax.
Yes, a finger can break the skin wall.
Yes, a tampon can also break the skin wall.
If you're using tampons, your skin wall, or hymen, as it is called, is no longer there.
lots of things can break the hymen even riding a bicycle. you seem to be in a panic here, its natural for a teen to experiment ok, its better your doing this than having sex so relax first off. 2nd Ive read your ?'s and answered a couple I think your over worried about someone thinking you had sex, because of the yeast infection, but yeast infections usually occur not because of sex but because your body built up extra yeast a woman always has yeast and times it gets a overgrowth, expecially if you have had to take any antibiotics. dont worry you will be fine the doc will ask if you are sexually active and if you say no the doc wont say another word and he dosent tell anyone what the two of you discuss. take care
If you haven't had sex, your still a virgin, no matter what else you've put up there. If your worried about a tampon breaking off, take a good look after you take it out, before you flush it away to make sure it was still in-tack
