After doing the deed with a FWB, how soon should I wait to contact to keep her interested? By the way, if you say it was great, and she replies with "thanks"....should i drop the idea of contacting?

never tell your fwb/fuck buddy how good she can blow or ride you. Don't do that. Infact, try to stay away from talking about the quality of sex unless she brings it up. If she does bring it up saying how good u are, just reply organising another day to have sex on. She will think you've put her pussy on a pedestal and take advantage of when she wants your dick rather than when you want hers. Also, she will probably want sex less often.

Keep contact short and sweet and try not to text to often. Make sure you don't communicate much on a emotional level neither. Infact, a decent PUA, chief made a guide on managing FWB's here view-next-topic-vt84601.html?view=next
