I forgot, is sodomy Monica Lewinsky or Barney Frank?
Depends on which jurisdiction.
All of the above. The Georgia statute defined sodomy as "a sexual act involving the sex organs of one person and the mouth or anus of another." I believe most state laws had a similar definition.
Laws against consensual sodomy were struck down in 2004, and were seldom enforced before then. The laws against forcible sodomy, or aggravated sodomy as it's called in many jurisdictions, still stand. The difference between consensual and forcible sodomy is like the difference between fornication and rape.
