@polkadot1273,
Stay very clear in your mind that the only thing you're guaranteed to get in a **** buddy situation is sex.
If you want emotional support - well, that's where friends come in - and really, in my experience, FWB are really **** buddies not friends. People say FWB because it is more acceptable in their own minds.
If you met someone on a site to find someone to ****, that's not a friendship with ******* added, that's *******.
In the old days, FWB were friends/former partners who added ******* to the relationship. It started with friendships, not with *******.
