Look beyond a shared interest
Compatibility develops through conversation and behaviour, not a single profile keyword.
Compare expectations
Discuss the kind of relationship you want, how often you like to communicate and whether your schedules fit. Two people can both be interested in pegging and still want very different kinds of connection. Finding that out early can save confusion.
Notice how disagreement feels
Pay attention to how someone responds when you prefer a different plan or a slower pace. A useful conversation allows both people to speak and does not require either to minimise a boundary to keep the other interested.
Let an unsuitable match remain unsuitable
You do not need to prove that either person is wrong to decide not to continue. Be honest about your decision and avoid making promises just to soften the moment. Shared interests can be valuable without making every pairing a good match.
