I don't know where to begin with you, Angie.
First of all, anything sexual that happens without consent in every state in the United States is rape or sexual assault. Whether it's between a man and a woman, a man and a man or a woman and a woman.
If you don't want to have anal sex with someone, and they force it on you, that's rape. Doesn't matter if you've agreed to anything else like vaginal intercourse - if you don't want anal sex, but someone has it with you, it's rape.
That said, some people (male and female) enjoy anal sex. No one, single lube has a monopoly on making it pleasurable, though.
Finally, your last part? We don't go for generalizations much around here. Not every guy is wants anal sex much less is "always thinking about" it.
Edited to add: Also, Angie, we don't allow users to display contact info here, so I'm going to edit out your email address, and ask that you please remove it from your signature.
