I am older, and have not found any of that to be true. As a lady, more makes more; more sex makes sex feel better and it’s easier to get off, and sexual frustration does not make me creative at all, just distracted and frustrated.

There is also physical benefit to sex for older women, I don’t know if it’s the same for younger, but certainly after menopause sex prevents vaginal atrophy and prolapse of internal organs, it’s sort of a use it or lose it situation. Penetration and orgasms are good for muscle tone, apparently. Beyond the obvious benefits of pleasure and relationship building.
