Was I groomed by my now ex boyfriend?

Going anonymous for obvious reasons. When I was 16( I'm 20 now), my ex messaged me on Instagram and we chatted for a couple days. I got to know that he's 9 years older than me, meaning he was 25, a full fledged adult, messaging a school going teenager. At that time I thought it was "cool" and "edgy" that an older guy was into me. He insisted on starting a relationship, and I had really low self-esteem back then, so I thought that if I say no, no one else would ever date me. I agreed, and it went on for a couple months. We never got physical, we didn't even kiss each other, and I was hesitant about even letting him hold my hand. He used to talk sexual stuff with me, even went as far as saying that my boobs are small and he could "do something about it". This worsened my insecurities but I still didn't want to get physical with him. Because of all these crippling insecurities, I broke up with him and he was surprisingly understanding about it. But now that I look back, I'm conflicted because he didn't really give me predatory such as forcing me to get physical and creating a scene about breaking up , but at the same time he commented negatively about my chest, knew my age and still chose to date me. Was he grooming me? Or I'm just over analyzing?
