Is my value ruined since I had sex before marriage?

I’m only 21 and I’m a female and I’ve come to a realization that giving my body to men that I’m not married to is quite literally pointless. I’ve learned that given the way I look from the first glance that no matter what all the men that approach me want one thing and we know what that is. I now have made a vow to myself that the next man that I have sex with will be my husband. However I am a little hesitant and worried that it’ll be almost impossible because a lot of people have said it’s not fair to make a man wait when you’ve given it to other men for less. In which I don’t plan on keeping any part of myself a secret they will know. So now I’m just here to ask who has had sex before and then decided to wait after the fact and how did that experience and process go?
