been having intercourse for 2 years plus now, only recently been having this weird sensation at the mouth of vjj when inserting. Tight, small amount of aching and tiny feeling of burning. only when inserting, once its fully in, the sensation will go away. and when inserting no choice we had to do it bit by bit, as the sensation is a little unbearable. there is no sign of dryness too, while inserting it is always lubricated. thought might had hurt/injure the bottom part, did try resting it for a month plus before trying it again. the sensation did not go away. suspecting UTI but doesn't has any other symptom. anyone else experience this or has any idea what is going on. should i seek medical help?
