You got to be joking....
And this is one of the many things I loath about being incel and belonging to an online community. Low Iq people like yourself. No offense.
First off. Many of these grannies are going though menopause or are post-menopausal. Their hormones are in the shitcan. Many of whom can't even get wet without lubrication. In addition to being out of shape (for the most part) aside from a few cougars, and don't have much energy in general.
The few cougars that fuck with young studs is mostly for the validation. It's not like they have an insatiable appetite for cock, otherwise they would get with normie looking young guys that have lower standards than a chad and be more open to fucking an old woman in the first place.
Even the few old bags that still have sex with their husbands on occasion, are doing so mostly to satisfy him, and/or still feel an emotional connection, have fun, and feel desirable.
Don't get me wrong. I'm not saying that grannies or women in general don't enjoy sex at all, but it's not nearly to the degree that 90% of men do, and it's MUCH less on their minds as well. Some women are high libido lymphos. Most are not.
