I tried for years, lost track of haw many 3, 5, 8, I just don't remember. I got every variation of NO you could possibly imagine. I hammered her most every day, sometimes multiple times, it was clearly badgering. In direct an subtle ways.
THEN
In September 2018 she had reached her limit and agreed to do it once and ONCE ONLY to 'shut me up'.
Since Sept 2018 till we locked down due to CV19 she had sex 101 different men, many repeats, 2 'regulars' and 2 gang bangs.
NO is NO until it isn't.
