Being FwB with someone means that one or both of the friend(s) is engaging in some sort of sexual relation with the other,for example,grabbing a friends booty or poking there boobs/dick.Maybe something more steamy like full on sex occasionally.If you are FwB with a friend or a best friend no less then you will he friends for a very long time.FwB tend to last longer than just regular friends and
best friends with benifits are usually around for life,because

best interest at heart.So in conclusion don't be mad at touching,welcome it if it's a friend you trust.
