A non-exclusive relationship. Can involve people being honest and on the level with each other, or cheating on or lying to others.
It can be a positive relationship where people who don't want to be
alone, but aren't wanting or able to be in a full-
time/exclusive relationship, can have a
friend to do activities with. It can be
sex based, or include other activities and sharing. It can be more than just a friends with benefits relationship as well.
It can also be a negative relationship, where one is cheating or leading on a partner and avoiding being exclusive. It can be just about
sex, it depends on the individuals involved.
After my divorce, and with kids and
work, I don't want a guy around all the time right now, but I would
like a part time
boyfriend.
