Men will say all the right things to get in your underwear then say all the wrong things to break up after getting in your underwear right?

You don't have to give Men anything you yourself don't want to give them within reason. If you're not ready for a physical relationship with a Man then be very honest and upfront about this. If he respects you, then he can handle that accordingly and move along. You have every right to say "No" to that if that's not what you want at this point in your life. I've said "No" and it's paid more dividends for me personally and otherwise than I could've ever imagined. Be honest about yourself and who you are and you don't have these issues, I don't because I refuse and reject out of hand any Mind games whatsoever. I'M NOT GOING TO PLAY THOSE TYPE OF GAMES. Stay true to yourself and your Self Respect and you won't ever have these problems...
