Ex number 1 would be over 150 per hour. 5'7", size 10, huge tits and was sex mad.
Ex number 2 would be lucky to get 60 per hour. Petite to the point of anorexic, no tits, frigid.
The wife would probably get 100 to 120. Size 10, good body, great tits. Average facially, no anal and can't suck cock to save her life but enthusiastic and willing in all other areas
