Getting fucked from behind can be a real pleasure, feeling those hands grab your tits, squeeze those nipples, rub them with their thumbs as you get pounded behind like a little whore. Elbows down, ass up, feeling that dick glide in from behind. Some will also enjoy being grabbed by the throat and being treated a bit roughly. Balls slapping against the ass with every thrust, G spot being stimulated, can feel very fucking hot and primal.
Usually when I ask a guy his favorite sexual position, this is the most popular answer, the most animalistic one of all. Getting fucked like the animals do it. For the woman, it can be not the most comfortable of positions, if on all fours, a bigger girl might have pain with the knees, bending over standing up would be the better option, though the weight of a hanging tummy might prove painful for the back, you just have to figure out what works best for both of you comfort wise.
All positions will not work with all people and be comfortable, you need to see what feels best with your body types, but many men seem to love the primitive doggy style. Not all men are seeking love and intimacy from sexual encounters and fucking from behind is just that, fucking, screwing, having sex, not the more intimate face to face making love some would prefer when being with another person sexually. It’s not for everyone, but many love it and for variety, there’s nothing wrong with mixing it up once in a while.
