My vagina is tight for speculum, intercourse and fingering. I try to stretch it by fingering. I can enter two fingers into my vagina, only and I have pain. (Gynecologist says that I should try three fingers but I cannot do it.)
Do you recommend something to stretch the vagina? ( I tried painkillers, muscle relaxants, lubricants).
It looks like you have some form of vaginismus (unconscious tightening of your vaginal muscles) or vulvodynia (a more general term for pain when entering something into your vagina). Dilators can certainly help with vaginismus, together with other methods (sexologist, physiotherapy, ...).
However, I would also check with other doctors or gynaecologists to get a more correct diagnoses and to build a plan on how to get rid of this problem.
A lot of (older) gynaecologists underestimate this problem or they even haven't heart about it. Because of this, a lot of women are having this (big) problem for ages, without that somebody helps them. To be honest, it looks like your gynaecologist is the same. The remark about the fingers is wrong. He or she might be a good doctor on some levels, but solving vaginal pain is not one of them.
Best is to search for a doctor that is specialised in one these areas. If you cannot find them, try looking for a younger doctor and ask them if they have experience with this. They are now teaching it more and more in universities.
I know you will have a lot of awkward conversations with this doctor, but it will certainly help you!
