Practice for First Kiss?? Help!

Rebecca • 19, college student
Should I make out with my girl best friend to practice for my first kiss with a boy that I like? We're not lesbians, but we're totally fine with kissing each other. I just don't know if I want her to be my first kiss. But I wanna practice before making out with a boy and this is the only plausible way. 
EDIT: This isn't weird in my high school. Girls make out with other girls for fun all the time.
