I attempted the this challenge with my ex and I believe it was around the 7th time for me I was so scared to even sit down, take a whizz, or walk. I believe she made it to 12, but them wimmens can last like no other, holy hell.
3 in the space of like two hours... fapping that is. second time was pretty hard to do... third time, my arm was so sore it isn't funny...
As for sex, once... went for two, but ran out of energy before I could xD
No idea. The most times in a day I orgasmed masturbating was 3 or 4, and I've orgasmed about 5 times or more during a single intercourse a few times. I have multiple orgasms, is hard to keep the count, so I don't really bother, usually my husband notices them more than I do.
12 with sex. (Threesome with two girls, threesome with a guy and girl, then continued sex with the girl).
15 with masturbating, I think. I tend to lose track when it gets up there.
1,2,3: woke up with morning wood from the tree of "vitality". 4,5: current XGF came over after parents left house. 6: whilst spooning thought I heard my mother's car pull up. 7,8,9,10,11,12: My parents were gone for a long time, started to hurt so she gave an oragel BJ. 13,14: got a text inviting me to a "sleepover" 15&1/2: halfasleep dream sex during which I blacked out/fainted.
