I'm FWB with this girl for about 3 months now. We fuck twice a week and the sex is fantastic. She treats me like a fucking king.

Every now and then she brings something for me when she comes over. Last week she went on a trip overseas and bought me some souvenirs for example.

Anyway, her birthday is coming and I'm thinking about buying her a gift. Do any of you ever do that to your FWB? Could this have any negative impact (i.e. her thinking we're committed)?
