uhhhhh weird question

I've been attracted to girls as long as I can remember but it was really hard to find a girl I liked and got along with well enough to date. But there were plenty of guys. After a long relationship ending I have a fling with my best friend. She's amazing and makes me so happy. I've never done anything more than making out with a girl and I've given and received some hickies--- we're starting to cuddle and kiss and stuff but before it goes to far, what do I do? I honestly don't have time to sit down and just watch porn or something
