In any case, one of the comments made an impression:
AMAZING writing. I really appreciate having stumbled upon this, as it has really made me wonder about my own life – I am 22 and have been in a serious relationship for two years. He’s amazing, and I think he might be “the One”, but he is the only man I have ever slept with. This bothers me because I am quite confident that if we were to ever break up, I would undoubtedly embrace “sluthood” – and I really feel like I may be missing out on something that is important for defining who I am. I discovered who I am sexually through my relationship with him. But I love him to bits so this is just something I will need to wonder about for the rest of my life? *Sigh* if only I had slutted it up earlier.I find this so sad.
Dear Ahria: There are innumerable women who would love to find "the One," just one  man who is amazing and build a life with him. That you've done so at 22 means you are ahead of the curve. Be grateful. Be happy. Treat him right, make a commitment, raise some kids. Do not spend even one minute regretting the fact that you were never an unpaid prostitute or that you didn't spend your young womanhood under sweating strangers who care nothing for you. The fact that you've thought about this, that you've gone so far as to put this desire into words and post it on a public forum tells me that you are tempted. But do not - do NOT - toss away respect and love for cheap - or, rather, very expensive - sex. Sex does not define you. You define you. Your good choices will make that definition worth reading.
Recently there have been several books published highlighting the effects of women who made the choice you are thinking about making. These are cautionary tales. They do not have happy endings. You have something great; don't get greedy now.
