Oh... Van the Man....with the emphasis on 'man' obviously. Sex between m/f and f/f is as different as driving a volkswagan beetle to a Lambo.
In short (I could elaborate quite extensively) M/F lovemaking is akin to a project with a definite end goal in mind. Fire it up, hop on (in) and rev that engine until it explodes in so-called ecstasy and all is well in the universe. Everything stops at that point and the male reaches for the TV remote.
F/F lovemaking on the other hand is akin to 'just being there in the moment', no drag race, no mountain to climb; just grasping the wonderful moment of two bodies bonded to each other in touch, smell, and thoughts. It goes on for hours sometimes, a real schedule buster especially if one has appointments or whatever. Time ceases to exist. We really do get off on each other. With my hub however I could set my watch to meet any appointment I might have. At 10 past 6 every morning ( or near every morning) the erection on the other side of the bed gets tossed over to my side and by 16 past 6 he's in the shower singing his gorgeous head off. And like most males he thinks he's performed a masterpiece. I still love him though.
I could go on but I've work to do. In closing, M/F sex is physical......F/F sex is spiritual. Women are spiritual beings...men are conquerers. And I might add...long live the difference. A.
