Never had an orgasm!

Hannah
Hi guys! So, I've been with my boyfriend for around 6 months. We are pretty sexually active. Have sex about once or twice a week. But, I've NEVER been able to have an orgasm. Not even feel like I'm going to have one. We have tried EVERYTHING. He feels so bad because he feels like he isn't pleasuring me well enough. Any tips? Is my vagina broken? Haha.
