What is the oldest and the youngest partner you have sucked or fucked?

I understand not everyone asks ages when we have a willing sex partner.

My oldest was a near-white haired gentleman. I was in a room at a Denver gay bathhouse being sucked so he walked up to me and put his cock in my face. I accepted the offer and sucked his cock.

My youngest was probably late teens. Again, I was in a gay bathhouse, in San Jose, watching porn in the video room. He laid beside me and we immediately stroked each others cock. Before long we were in 69 enjoying each other till we both swallowed a mouthful of cum.

So lets say oldest in his 70s and youngest 19.
