I will briefly say that I have done one and only one back when I was in my late 20s. There were 6-7 men, as some left, others showed up, some who left came back, so I sort of lost count. It was very exhausting as I sometimes had three men working me over, plus a portion of the session involved men 'pulling the train' too.
I'd prefer doing two or maybe three men. Much more manageable.
