Dating a stranger or a simple one night stand encounter can give you the release you need, and if you keep it discreet, everyone can stay happy.
Many people would be shocked to learn the statistics regarding extra-marital dalliances.
Adult dating is easy to do online, as you can join free, browse profiles and photos, and find fellow married adulterers in your area to chat with.
You can then decide if you want to meet for something more.
Both parties need to keep the affair secret, so both will respect that and there is little chance of being found out.
