Hi
I would recommend making an appointment at our provincial STI clinic just click here for information on the clinic and how to make an appointment.
The nurses that work at this clinic are experienced in sexual health matters and you can discuss topics about sexual health, masturbation, genitals etc.…
You could also discuss the exam with the nurse you see, just let them know what you are concerned about. In your situation, they will usually just do an examination of the external genital with no need to put anything in the Vagina. Just do what is comfortable for you, there is also no need for an exam if you just prefer to talk on your first visit.
With what you have described I am thinking that the spongy block you are hitting is your cervix. Everyone’s genitals are different with people having different size clitoris, labia and depth of the vaginal canal.
