In the doggie style position, the changes in the angle of penetration can be even more intense than in the missionary position.  Like the missionary position, the more parallel the man's body is to the woman's, the more full body contact there is.  This allows for more kissing of the woman's back and neck, and caressing of the woman's breast.

Also like the missionary position, the more perpendicular the man's body is to the woman's, the deeper the penetration is and the more friction there is.  This is because the male's erect cock angles upward, so any time he is having sex in a position where the top side of his cock has more pressure put on it inside the woman's vagina, the more friction there will be.

The doggie style position doesn't allow for clitoral stimulation of any kind from the male's body since it is pressed against the woman's ass rather than the front of her pelvis, so the man or woman should use their fingers to stimulate the woman's clit during intercourse to help her achieve orgasm.

While anal sex is possible in almost any position, doggie style is the typical position people think of for having anal sex because of the easy access it offers the man to the woman's ass.

The same changes occur in any rear entry position, including Female Superior positions such as the the Reverse Cowgirl.
