My boyfriend and I were engaging in sexual intercourse last night. During our intimate time, he stopped and asked "what's that?" Not knowing what he was talking about, I felt around and noticed a ball-like bump inside one of my folds next to my clitoris. Worried, I checked it out in the bathroom. It isn't noticeable just by looking, it doesn't hurt even when being touched / adding pressure to it, and there's no discoloration of any sort. My boyfriend thinks I should wait it out a few days before getting checked, in case it's something small like a broken blood vessel. But because of its odd feeling I'm worried and want to know if it's worth getting checked. If anyone can tell me what this is or what it could be, I'd appreciate it greatly.
Thank you
