Is it normal that two girl bffs like to make each other horny and make out

Hi! We are two best friends, both girls. We are both seniors in high school, but we live across the country from each other. After I moved, we started getting closer, and still get closer and closer everyday. We talk nonstop, and share everything in our lives with each other. We text all day long, and talk for hours on the phone daily. We love each other SO much-- more than anything.

We are so open and comfortable with talking about anything. We've recently started talking and joking about masturbating and new tips and techniques to try. We are very funny about this, and just want to make each other happy. We have always showered together, and are fine being naked around each other. We LOVE cuddling and snuggling, and act like a couple. People have asked if we are a couple/ if we are lesbian. They are often confused at how much we love each other, and love talking to each other all the time.

Every visit since I've moved, we've experimented more sexually. We spent this past summer together, and began kissing and making out and dry humping to the point of orgasm sometimes. We are not sexually attracted to each other, but we love to squish each others cheeks and give big squishy hugs, etc. We love to make each other happy. We constantly have deep talks about our futures together, and we hope and think that we will be best friends for the rest of our lives. There is so much more to our relationship than just the "sex". We get so excited during visits because we only see each other in person a few times a year, for short periods of time.

This last visit, we started "tickling" each others' boobs and lower stomachs, and during our last make-out/hump session, we rubbed each others' vaginas over underwear a bit, so we both could orgasm. We both think we are straight, and it's just that we love each other and love having fun with each other.

Neither of us could imagine being sexual with any other girl, except each other. We are so comfortable with each other, and don't have many boys in either of our lives at the moment, so it's fun and satisfying. IIN? Are we bi? Has anyone else had an experience/ relationship like this? Thanks!
