Rule 1: define what “casual” means to each of you
Casual can mean non-exclusive, low-frequency, emotionally light, or simply “not a committed relationship.” Those are not interchangeable. Say what you mean instead of assuming the same word creates the same expectations.
Rule 2: make consent ongoing
Agreeing to an FWB arrangement is not blanket consent to future sex, specific activities, visits or communication. Either person can change their mind at any time. A good arrangement makes room for a no without punishment or manipulation.
Rule 3: discuss sexual health explicitly
Talk about protection, testing, other partners and what information you expect to share if circumstances change. Avoid treating sexual-health conversations as mood-killers; they are part of informed consent.
Rule 4: decide what exclusivity means
Some FWB relationships are exclusive; many are not. If exclusivity matters to either person, discuss it directly. Do not infer exclusivity from frequency, sleepovers, affection or the fact that neither person has mentioned anyone else.
Rule 5: revisit the arrangement when feelings change
People are allowed to become more attached, less interested or interested in something different. The responsible response is not to hide those changes indefinitely. A check-in can lead to continuing, redefining or ending the relationship.
Rule 6: keep privacy and dignity intact
Do not use private details, photos or messages as social currency. Friends-with-benefits still involves trust. Respectful endings and discretion matter even when the relationship was intentionally casual.
