What is your intent? If you are going to be wading around the polluted waters of online dating and dealing with men, then relentlessly pursuing your intent will cut down on wasted time on scrotes.

Let's say your intent is a LTR. Don't let your date know that immediately, but allow him to show through his words and actions that he is LTR material. If you conclude he is NOT LTR material, but perhaps better suited for "casual" or "fwb" then block and delete. Every minute you spend on what you DON"T want is a minuted wasted in pursuing what you DO want. Yes, you might be lonely and wanting sex, but "settling" for a casual or FWB just distracts you from your goal. Pursue your intent relentlessly and don't get sidetracked from it.
