OMG! If my close friend gets on benefit I can expect phone calls every week! (yeah we have that relationship). Am happy hearing from him ONCE a month by call. He pushes it after 3 weeks. Sometimes even two! If he was on benefit? Especially the convo will go bad to dreadful!

I don't see any issue with it, although it usually ends up with one or the other parties developing stronger feelings, and it can then become difficult.

It can work with the right person. Has to be for fun only.

I have never had friends with benefits so can't help much here:)

Interesting.... Never tried such with a friend. Can see a number of pitfalls that one might encounter, but it would be dependent upon the friends. As well as if there were significant others in the picture.

what about an online FWB?

I don't care if my friends are on benefits

I don't think there's any such thing--not sustainably. The benefits will change the friendship
