Sounds so nice.
You just help a friend out once in a while.
- drive them to the airport
- take them some chicken soup when they are sick
- have a little sex with them when they are in between relationships
How nice, how helpful, how totally not going to work.
I read about a couple who were out in a sailboat. They decided to go for a swim, and since no one was around they decided to swim without the hinderance of clothes. Everything seemed fine while they were paying attention to each other, but then they noticed that the boat was drifting away. The sails were up and it was moving faster than they could swim. Eventually someone spotted the boat and search and rescue started looking for the occupants of the boat and they were pulled safely from the water. For most of us it would be a little embarrassing to have a couple of guys grab ahold of your arms and pull you into the rescue boat realizing that they knew you were dumb enough to let your boat get away. And it would be even more embarrassing if we were naked when they did it.
Friends with benefits it like that. I seems like a good idea, but it ends up badly.
Unless the sex is really bad, one or the other of the friends is going to start having feelings and will start mixing in love, romance, relationship, and even thoughts of marriage.
Friends don’t let friends have sex with them.
