I just started doing bjj and joined a gym. I went with a blue belt and thought I could submit. I got close a few times but he knew exactly what to do and it ended in me giving up a submission. This happen two times in a row then the third time we rolled I decided to survive. He got me into a lot of uncomfortable positions where my neck and other limbs hurt but I knew it wouldn't break or tear anything. It ended in a stalemate but he had a lot of dominant positions. If you're just rolling do you tap from pain holds? The next day I was sore as hell from muscle stretching but no injuries.
