Why does sexual intercourse hurt!? (Possibly NSFW)

I’m in my early 20s, and lost my virginity about 2 years ago. I have trouble finding sex enjoyable because it hurts too much. I have only been with one person and it’s really starting to affect our sex life as often I don’t feel like doing anything or we have to stop. It only hurts during and it’s usually a deep sharp pain towards the left side… but sometimes the whole pelvic region just feels pressure and a dull but strong pain.

I know that my uterus is tilted slightly and that I have fibroids(?)... this was found on an ultrasound but the doctor was not all that concerned and kind of ignored it because she said it should not be painful.

Any ideas?? What should I do?
