Start thinking about waiting 6 months before before having sex with a guy. If he won't wait, he just wants sex, period

Sorry you got your heart dented a bit....that sux. Just chalk it up to a life lesson and forget about it. Everyone makes mistakes.

If he still is interested in you he will make time to see you, talk to you and make time to spend time together.

Don't chase after him. Theres no need. You don't want to be with someone that has no interest in you other than sex. Thats pointless.
(unless thats what you want...then more power to you )

however...if your looking for someone to have a relationship with.....

If he calls and wants to "hang out" tell him the two of you can "hang out" at the coffee shop...or go to a movie. Don't allow it to go to the bedroom. If he wants you he will persue you...take you out...call you...send you flowers...e-mail...

he will do these things without trying to make it about getting you into bed.
Make him work towards getting to know who you are...if he does not want to...then you know he is not the one for you.... and move on!
