Painful sex

For the past few months I have felt a sharp pain that almost feels like a lot of built up pressure whenever I have sex! It gets more intense during very penetrating (I hate that word lol) positions. I can feel it deep into my vaginal canal! It happens almost every time I have sex! I have only ever had one boyfriend and we both lost our virginity to each other about two years ago. I don’t have anything weird happening. No random bleeding, no strange discharge. I only have some light cramping in my lower abdomen sometimes! If anyone has had a similar experience could you let me know please! Thanks!!
