Just take it easy and make sure she is comfortable with you. A few mares do not like human males as mates, but they are in an extreme minority. I am amazed at how many take my first advance as something completely normal. Later, they become more demonstrative. I have a jenny who, whenever she sees me, will park out and pee short jets as she winks. I also have a mare who does exactly the same thing. Good luck with your adventure, and just treat her as an equal.
