Have you considered trying to use more foreplay and bringing in clit stimulating toys like a magic wand when penetration does happen? It might lessen the pain when you're thoroughly enjoying yourself. It's also possible that your body is actually negativity reacting to the pain you experience when you have sex. Another option is that you could try dhea supplements. But above all else talk to your boyfriend and have an open ended conversation about what you both need and what you're each willing to try.
