Maybe you had to much to drink or just got caught up in the moment, but you had sex with this great guy on your second date and you haven't heard from him since. Of course this has wounded your pride and made you feel like he probably thinks you are easy. However, you can never tell when is too soon for sex. Sometimes it can happen on the first date and still lead to a long and happy relationship. Other times, such as you are now experiencing, the man simply disappears.
So if there are no hard and fast rules that determine when to have sex in a relationship, you have to play it the way it is. What do you feel for this guy? Do you want a relationship or just date him again to save your pride? Your head is probably telling you to just forget it happened, but your heart is saying something else. However before you do something that will make you sorry, you have to sit down and be honest with yourself about your motives.
If you felt an electricity and think there could be a future, you should go for it. However, you have to do it in the right way and with your emotions under control. The act of sex can mean different things to a man than to a woman. Men are natural predators and always looking for a quickie that will not lead any farther. Women put a lot of emotion behind a sexual act and since they are natural nesters they usually want it to have a deeper meaning.
When he first met you, you were unattainable, like a princess in an ivory tower. It would be a challenge to cross the moat, slay the dragon and scale the walls of the tower to rescue you. The morning after he has sex with you, the challenge is gone. He might feel a little disillusioned that it was so easy and wonder if you fall in bed with every man you date. If you want to have a serious relationship with this guy, you will have to change the image he now has of you.
The way to change his image of you is to show him the woman you really are. This won't be an easy task, but it is possible. First you will have to have contact with him and that can be done by text, email or phone call, but however you do it, don't mention that you regret having sex so soon because you are trying to make him forget what happened and get a fresh start. Make your attitude one of cheerful friendliness. Invite him to lunch or the movies.
Everything will have to be on a friendly basis for a while. You have to see if you have enough in common to start a serious relationship. But by showing him by actions and not words that you aren't an easy mark, you will regain his respect. As to when to have sex again, let things develop and see what happens. However, don't let it happen too soon or you will be right back at square one.
