Yes I would
Read the letters in Penthouse with a friend. We started stroking our cocks. He ask me to stroke him and without asking I started sucking him. Had another friend I told this story to but left out the sucking part. We tried stroking and I sucked him. I know one before the other but I sort of lump them together as first blow job. Both about same size both two years older one cut one not. When they cum I wasn’t good at swallowing, didn’t really know it was a thing. In time I got it worked out.
