TS,
first I would like to say its great to see liberal women like you around who are not afraid to enjoy good sex.
However reality does bite and we still belong to a traditional Asian society despite SG's multinational metropolitan reputation. Ask yourself if establishing a family is one of your life goals. If it is, I would suggest you don't destroy your future happiness by becoming what we men call a easyrider. Take extra caution when selecting a FB, do protect yourself.
Sg is a terribly small place with tons of people knowing each another and people do like gossip. If the guy tires of you don't be surprised he'll pass your info to some other guy and let him take over. Your reputation can be tarnished over a single men's outing with a guy bragging about his conquests. We men can separate sex and feelings much better than women. With a easyrider reputation it will be tough to hook a decent life partner.
There are few things men wouldn't do for sex. Sex is one of our prime biological directives along with power & domination. Hence, lying is just a negligible hurdle for us. The unhappiness trick is one of the oldest tricks in the book. The main aim is to pander to your female ego that You are the ONLY one who can bring me relief, thereby increasing your self worth and stimulating your innate caregiver tendency as a woman. Its a cheap psychological illusion. Another very old trick is to steer the direction of the date to create a point where you're more open physically & emotionally to sex . Eg, slow walk on a desolate beach after a nice dinner to create privacy and lower inhibition. Talking about emotional stuff to bring you emotionally closer and allow you to empatise.
Let's just say men who are good at the game rarely learn this from teachers, its largely through experience. Which means he has done this probably with a lot of women.
Hope you gain a different perspective from this! Might get zapped for revealing trade secrets LOL.
