My friend, there really is nothing new that anyone can tell you. All the guys above gave you A+ advice especially Kinetic24.

You want the best of everything, but life doesn't go that way. If "experienced" girls really bother you, then maybe you are ready to settle down and stop sleeping around. So the solution is to make changes to your lifestyle, and then hang out in places where "pure girls" hang out so you can find your angelic pure wife.

When you meet your perfect pure girl, you will have to marry her, because that's what pure girls usually want, seeing as turning down horny guys is how they stayed pure in the first place. After some months of being married to her, she will gain experience and you will have your pure girl with experience.

If you don't want to settle down, then you have to accept that logically, the girls who decide to sleep with you outside of marriage, would have slept with other guys before you. That is how people get experienced in anything: they do it over and over again. Time to use the logical part of your brain to settle this in your mind. This dilemna you have will easily be resolved with just some cold hard logic.

Like I said, the guys gave you sound advice already, not sure what else you wanted to hear. You asked how to deal with this? Through some straight logical thinking, is how.

It's 2015, get with the program

As to the feelings of inadequacy, drop comparing with is based in the ego. Remember, you are the fucking MAN and you are the king of your castle. Not feeling this way will be picked up on by the woman, guaranteed.
