I [FtM] asked my friend if I could ride him [M]

First time poster here.
Little background about me. I’ve identified as a lesbian for about 8 years and have only slept with women prior. When I started deconstructing my gender, I also began to deconstruct my boundaries on sexuality and realized that I like to fuck, I don’t care what the other person has going on in their pants. Lol. I’m petite, have had top surgery, and think I’m overall a pretty cute and dapper kind of guy.

Anyway, we’ll call my friend Ed.
Ed has been a great friend of mine since freshman year college, it’s been about 6 years of strictly platonic videogames, horror movies, smoking weed and overall having a good time. He’s a bit of a nerd, but in a way that seems like he’d be really good in bed, if that makes sense?
Earlier in the day I had been sexting with a stranger online and I was squirming throughout the entirety of the day. I wanted to get off, but no matter how much I’d use my showerhead, I’d cum multiple times and still crave the real thing. I knew Ed was coming over later in the day and I had these ruminating thoughts of how I could ask to suck him off in the car, but I was nervous that would detour him based on our prior relationship.
I began creating scenarios to ask to grind on his dick. “I’ll tell him it’s too cold to go shopping, we can watch a movie, get stoned, and snuggle up.”
It worked.
