Have you ever been on a date with that man? If so, then do not hesitate to compliment him on something you really liked. That might be the time you spent together, the conversation that you enjoyed, the meals or the wine. Maybe he impressed you with his intelligence or looks? Men love flattery. Just do not overdo it so that your text wouldn’t sound too fake. Try and sound as sincere and frank as possible. If you do it right, it’s very possible the guy will ask you on a second date.
