hard time climaxing

Okay, so I love sex a lot and I have it a lot, but I don't seem to orgasm at all during sex. The only times I orgasm is when I use a toy. My boyfriend is amazing and I feel like I'm closer every time we have sex but I'm still not getting there. Is there anything, toys, positions we can try so that I can finish too? Or things that'll help me relax and just give in to the feeling? Like I'm not sure what's holding me back, so anything you give me will be helpful!! Thank you!
