5 times sex with my wife in a hotel room all day long, the last time was very tiring and hard to stay motivated, cumming didn't feel that great but at least we fucked! Only other major sex day was 4 times on vacation and the third time included anal, which was rare as we don't do anal even once a year.
7 times masturbating starting at about 7am and ending 9pm. I was going for 8 times but wasted time in the afternoon and missed my chance.
Not cumming: my wife and I fucked 15 times on our 15th anniversary but I only came on the 15th time! That was a fun day, she had at least 2 Os every time, we did it all over the house, all kinds of positions, it was radical. Hope to replicate it one day soon!
