Fuck buddies
If you want to get laid regularly, but don't want to commit to a heavy relationship then a fuck buddy can be ideal.
It can be a real thrill to have a passionate fling with someone you wouldn't normally hang out with much. Sometimes a couple has incredible sexual chemistry, but beyond that they have little in common. The added sense of naughtiness allows some people to cut loose and play out their fantasies.
Both partners have to be very clear about what they want from having a fuck buddy, and need to talk about their expectations so that there are no misunderstandings.
