I'm going to lose my virginity to a woman 14 years older than I am
Why did you choose someone so much older?
I always wanted to have sex with this woman.
If you like her, and she likes you, then that's great. You're old enough to choose who you're going to sleep with.
I don't care. I just hope it's worth it. I didn't think I was ever going to lose my virginity.
Well it sounds like you have found a fulfilling relationship and you are probably ready to take that next step.  Since neither of you is a minor, then there is nothing wrong with the age difference, and nobody should tell you otherwise.  I hope everything works out for you both.
