How old were you saw your first 'monster dick'? When I was 6 I joined an acrobatic club. there were 2 guys and loads of girls. The first day when I went to get changed I walked in on the other 2 guys, 1 naked with a huge erection the other jerking him off. I watched until he shot across the floor, then he came over to me and asked me to try and hold his still-hard cock. The next session I tried shaking it for him but it needed more than my tiny hands to get a grip so all 3 of us shook it until he came. He can't have been any older than 13 but this was some introduction to contortionism and acrobatics
