What Could Cause Itchy Bumps On Labia, Painful Intercourse And Subsequent Spotting?

hi

i have a straight line of tiny taste bud like bumps on my outer labia. they itch a lot and swell at times. i also have painful vaginal intercourse. the penis hits a wall that causes a sharp paint hat radiates towards my anus. i dont know if i bled after intercourse as i usually have spotting 3-4 days after my period ends. i used to take the morning pill before, took it for almost 10-12 times 2 years ago and have been having spotting ever since. I was diagnosed with fallopian tube infections once. i have had ultrasounds done regularly till last year and reports were normal.

please help.
