TIFU by getting a boner while cuddling with a platonic friend?

I, 17M, decided to hang out with my female friend (17F) at her place. things were chill and we were watching something on youtube and grabbed my arm and put it around her. She's really touchy with everyone so i'd didn't really think anything of it. then we started getting more comfy, and near the end of us hanging out, she put her thigh on me as we were holding each other. and would you know it, right on my junk. at that point i already had a boner and she made it worse just by that. i'm sure she could feel it since i don't have a micropenis, but she didn't move her leg at all. i just don't want her to think im weird or anything. would she have said something?

TL;DR, I got a boner while cuddling with a freind and don't know if she felt uncomfortable by it
