All of which just means you're insecure. When you mature a bit you'll begin to appreciate the true value of a woman who, like anyone mature, has had successes and failures, lived and learned, picked up ideas from having had some experience, and so on. You'll see.For the short-term maybe. But if I'm going to be in a relationship with a girl, she better not have had over three cocks at my age. Nothing casual for her either; all her encounters must have happened in the context of a relationship. And yes, handjobs/fingering count, ladies.
As for the "are all women sluts" question. No, unfortunately. Though I'm being a bit facetious, of course. The good ones are partially slutty but also have values, which means you can trust them but they'll rock you at home rather than star fish you to death.
