Virginia is not generally not known for the fact that it has progressive laws about sex and the like. This is why it is so often considered one of the worst states in the country, especially where things like sex and marriage are concerned. If you want to know why Virginia is considered such a prudish state, just look at their laws concerning sex practices that are not just harmless, they are widespread and widely considered valid ways to engage in sexual behavior as well!
One activity that can actually get you thrown in jail if someone chooses to prosecute you for it is phone sex. A lot of people engage in phone sex for a variety of reasons. One of the reasons is, of course, the fact that sex might not be an option for you. You or your partner might not want to go all the way, perhaps there is geographical distance that makes actual sex difficult, perhaps you just want to have phone sex. This would actually be a crime in the state of Virginia because of the fact that the legislators in the state consider phone sex to be lewd behavior, unbecoming of good Christian citizens.
A lot of the laws in Virginia come from the fact that the legislators have Christian values, but it is important to remember that a lot of these Christian values are actually misinterpreted or distorted to force a specific kind of lifestyle on an entire group of people that might want to live life in their own way.
Phone sex is also a crime to prevent homosexuality, since because of sodomy laws and the like many homosexual individuals would choose to have phone sex in order to maintain some kind of sexual contact without having to worry about the kind of legal ramifications that would have arisen from them choosing to actually have sex. In order to prevent all homosexual activity from happening completely, Virginia legislators chose to make phone sex a crime.
Another reason that phone sex was made a crime was because of the fact that it was often used as a way around the fact that prostitution is outlawed. Having sex over the phone used to be a legal act which meant that people often charged for it. Outlawing phone sex entirely was the solution that Virginia legislators ended up going with for whatever reason, thus making it more difficult for phone sex operators to continue their business.
It is important to realize that you are probably not going to get prosecuted for having phone sex, at least not in this day and age. People are probably going to laugh at the very thought of such a thing in fact. Still, the law certainly still exists and it is probably not going to be repealed any time soon because of the fact that Virginia is still a very conservative state with a lot of backwards ideas about sex.
