TMI - very small vagina, what to do?

[awkwardnamechange]

I've named changed for this because I am wayy too embarrassed to post this under my usual name! I know it's TMI, but I figured women's health would probably cover these things.
I'm early 20s, never had penetrative sex, never used a tampon or mooncup. Periods etc normal as far as I know, started at 14.
The problem is, my fanny is tiny. I mean the vagina. If I'm very relaxed I can just about get the tip of my little finger in before it's too narrow and hurts, there's no way I could get a tampon in and I assume that penetrative sex would be very painful. My question is, should I speak to a doctor about it? Is it likely to cause me any issues? (apart from no sex, which I can deal with for now in covid times anyway) Is there something vastly wrong with me?

Lots of people are going to assume you are a troll. But even if you are there must be others who feel like this so I'll answer (and I'm not trying to offend you if you're for real).

If this is not causing you any problems I would not do anything for now. The vagina is extremely stretchy to accommodate a range of situations. I suspect it is psychological (the muscle is tensing) rather than a physical issue.

If you want to use tampons and can't or have difficulty with smear tests (I'm not sure when they do them now), yes, see a doctor. Otherwise just relax about it until it becomes an actual issue.

Surely the suggestion is to go to the GP and get a professional to check you out, there not much a Internet room of strangers can tell you- except if you're a troll looking for hand time material (not envy)

....but in the case you're genuine, talk to GP.

Absolutely read up on the nhs link above about vaginismus
The muscles themselves are extremely flexible, but it is really common to for a physiological process to cause them to tense up

id go to the doctor and get someone to check whether there are actually any physical differences. They might want to scan you to check that your reproductive tract is atypical etc, or it might be vaginismus

Bran makes a good point as well. So do consult your GP.

Yes actually I think on reflection my first post was not helpful. See the GP.

Thanks everyone, I'll have a look at that link and speak to my GP (although face to face consultations seem to be few and far between at the moment so I doubt I'll actually be seen). I didn't know vaginismus was a thing, I thought I was just weird. I did think when I posted that people would assume I was a troll, I promise I'm not! Although I am now very weirded out that someone gross might find this thread and use it to wank to - very glad I didn't use my normal username now!

@Awkwardnamechange Honestly, OP, if nothing has ever been in there, it's likely to be normal and your hymen. Look that one up! That's how most women are before every having sex or using tampons. It varies in everyone and sometimes is smaller or larger, or breaks easily, or not.

It doesn’t have to be psychological. Sometimes it’s down to very strong muscles.

This happened to me, and l was ‘stretched’ under GA. I was fine after that.
