The most common lie told by women in my experience is Please be gentle ive never done this before !!!

My wife said that to me a few times a year.

I can honestly said I have never spoken those words. Gentle is SO overrated! 😏

Women´s reasons are mysterious, even to them.
So, mine is only a speculative conjecture about ONE of those posible motivations (and I´m probaby wrong about).

There is a saying:
"Men regret the sex they didn´t have while women regret part of the experiences they actually had. Even if they enjoyed them at the time but looking at them from the present emotions."

May be, just may be, they count as not significative the ones they would not choose again, NOW. So it´s, somehow, "all new".

May be, just may be, the past experience were (as remembered today) so harmfull, alien to their actual self image or less than good enough, that they want to "recreate" and "overwright" it AS IF new.

This according to some experiences with ladies, but just saying.

fuck off

It's usually because some women are tired of bone dicked dumbasses climbing on them and trying to pound their asses through the mattress.
