Planning on my first real sexual experience with another girl on Friday - nerves are killing me.

First post, my heart is pounding. 21 year old female here. I have never hooked up with another girl since childhood, while just playing around. I've been fantasizing about sex with another woman for ages, and an opportunity has finally arisen.

On friday, I am planning on hooking up with a beautiful girl from work. I believe she is mostly straight, but also looking to have a lesbian experience. We have had graphic text sex with each other, and are both really into this prospect. We also have a "no-emotions" rule, which is fine, since I don't think I am emotionally attracted to women.

I'm so nervous, though. I know I can please her, but even though I know I'm told I'm pretty, I'm a bit heavier than she is, and so scared of female judgment. Also, I don't know how to act sexually with women! I've only had sex with men before, and I know how to act sexy with them, but I don't know how to do so with women.

r/bi, is there anything I should know/keep in mind when sexing this girl for the first time? I want it to be a hot, sensual, and comfortable experience for the both of us.

Thanks! :]
