I can understand your nerves! When I first started getting more physical with people I had no clue what to do with my pubic hair. I started shaving bc the person I was sleeping with liked it even though I didn't at all. It didn't feel good when I was getting touched. Now I trim, and I do it with scissors not an electric razor, (although both work great! I'm just sharing my personal experience). I like trimming bc I know when I go down on a girl it's sometimes hard to get her clit if there's too much hair there-it's just not that sexy to push pubic hair away from your face for me, (although some people don't mind at all which is also awesome!).

I know it can be really scary and nerve racking to talk to someone about what they like, and what you're willing to do, but I would try to do that. First, I would think about what i was willing to do, and give the person those options. Whatever works for you though!
