Help me πŸ˜‚πŸ˜‚πŸ€·πŸ»β€β™€οΈ

Just a lil long but PLEASE LMFAO. SO I am what I'm calling "newly gay" right? Literally first female I've ever had any feelings for. So there's this girl we've been hanging out for a little over a month and I like her ALOT. And so it's gotten to the point where she asked me to be her girlfriend and well after that part idk how to act? Like HOW do I be in a lesbian relationship. Like I feel like being in a relationship with a female vs. male us SO much different. And we have some mutual friends that she still kinda flirts with and it makes me so uncomfortable πŸ˜‚πŸ˜‚ like but im like, is this something normal that goes on Orr I should address the fact I'm uncomfortable? Lmfaoooo bottom line I don't wanna piss her off by not knowing how to do this but I really want to! πŸ˜‚πŸ˜‚ literally ANY helpful tips/advice/teaching lessons will be amazing πŸ˜­πŸ™„
