It's not necessarily normal. I haven't heard of a lot of guys who like that but stimulating a guys prostate (which is lokated in the anus) will help arouse him. So yes, in a way, it's normal.
These genotypes are determined by a human's 23rd pair of chromosomes. If the subject is female, she has two X's reading XX. If it is male, then his genotype will read XY. There is a 50-50 shot of each. This is because a woman donates one chromosome (she only has two X's so it is inevitable that she will donate an X), and a man donates one of his. If a man donates his 'X' then there will be two X's and the child will be female. If he donates his 'Y' then the child will be male. Male is XY, female is XX. There are, however, other genotypes (XXY, XXX, XO...) and not all people have a phenotype that goes with their genotype.
Yes, it is normal for some species to have both male and female reproductive organs, a condition known as hermaphroditism. This occurs in various organisms, including some plants, animals, and invertebrates.

Breast sex normally requires some type of lubrication, although that depends on the likes of those performing the act. Once lubricated the female normally presses or wraps her breasts around the male's penis. Once this is done the female can move her breasts, or her body, to stimulate the male, or the male may make thrusting motions to stimulate himself.
