Sex issues.. Help!

Anna
I'm 20 and I've never been able to have sex because it hurts so much. I've done research and read a lot about vaginismus but since I haven't been able to get over it I feel like it might be something more than that. My bf of 2+ years has been very patient and encouraging about it (which I'm very thankful for) but I hate that I can't fully have sex with him. I would greatly appreciate any tips or advice about this issue, or at least know that someone has similar issues so I know I'm not alone. Thanks
