My self harm scars

This morning a my bf friends was driving me home and me my bf are just sitting on the back seat he’s like laying down on my legs and he notices my scars on my thigh and he looks up at me and I kinda just shake my head no so he goes to lay back down kissing them and he falls asleep. Idkk if the next time we hangout he’s gonna ask me about it should I talk to him about it (I’m no longer cutting btw) ( and I know this is in the wrong topic I just need someone to answer please)
