I don't know how to tell if it is a cop on the internet, but in person the police whores are especially good looking, and they are tempting to me where with the real whores it is easy to resist the temptation. And they are more seductive than a real whore. That is why I call it entrapment. You might be enticed by one of these really good looking police whores where you would not be interested in a real whore.
I really don't know exactly what it means for a man to say that he is a virgin. You don't have a hymen in the first place. By the age of 21 you must have some experience even if you have never experience penile penetration of a vagina. There is nothing magical or mystical going to happen the first time that you do penetrate a vagina or ejaculate in a vagina. If you are really inexperienced maybe you have a female friend who will let you just give her a good physical examination your eyes or maybe she would let you eat pussy or get her off with your hand and let you see how her body works. You might not be all that inexperienced but I don't know what "virginity" means in relation to the male. But I do agree with the others that you would be better off to resist the temptation to fuck a whore. Male to male hook up is easy on craigslist but most of the ads on craigslist for female looking for male are just scams, and if you post an ad male looking for female most of the response will be scams. But the way young women put out these days, I just can't imagine that anyone would really need to resort to hiring a whore. Truckdrivers use lot lizards because we are not in one place long enough to meet a legitimate woman and have no vehicle suitable to leave the truckstop, and because the lot lizards are always there solicitating us. But as I said, I don't do whores because while I like to eat pussy and fuck my wife at home, I prefer the men for casual cocksucking when I am on the road, and they do it free. I don't want any pussy that has already been fucked by a thousand other men. I would imagine that even an older woman or a fat woman, or a woman who is not so goodlooking would be a lot better than a whore. Well good luck to you, I remember what it was like back when I was in high school and in those days all of the girls wanted to be "virgin" on the wedding night. My wife is the only girl friend that I have ever had, and she would not even let me look at her pussy in the light until we were in the 11th grade. I did not really want to eat pussy back then, but I kept talking about it to get her turned on so that she finally let me eat pussy and that is the first time that I really got to look at it in the light and satify my curiosity. Of course she kept her hymen and we did not have "go all the way" intercourse until our wedding night after finishing high school. So I know that it is real frustrating for you. Just remember that the very best orgasms you can have will be with your own hand.
