how to flirt with a girl?? 😳🙈😂

I have a boyfriend and he would be okay with me exploring with another woman.. I never have, and have wanted to since teens. I'm trying to go back to college and just want to have a better time here (it's in a different state vs where I had gone before) as well as GRADUATE this time mofo's haha. I haven't told many girl friends that I want to explore because of being judged or them thinking I would act differently with them, because I wouldn't since I don't have a crush on them and their my friends haha..
