For those of us who have fuck buddies or even girlfriends who talk about their sexual past (gasp), I bet that we all get a sinking, depressing feeling whenever we hear them recount their sexual experiences, e.g. their n-count, their sexcapades, what they did with whom, etc. etc. It's not per se that we're jealous that they did it with someone other than us; it's that we compare their experiences to our own, and then realize how "behind" or "inexperienced" we are. In fact, you'll even start hating women for how easy it is for them to get laid compared to us.
Never ever do this to yourself.
First, things are different for women; if you're a sexless male, you know how thirsty men are, and the extents that we'll go just to get some poon. Getting sex is UNBELIEVABLY EASY for even fat/ugly girls. There's just no comparison. It ain't even the same fucking sport. That's how lop-sided the sexual marketplace is.
Second, men tend to peak towards their 30s, while women experience a decline towards their late 20s. When they're disillusioned by the Cock Carousel, being pumped and dumped for the umpteenth time, and feel the societal/biological pressures to settle down and get married before it's too late, we're only beginning to come into form. If you compare yourself to a girl who's of the same age, you're literally comparing different stages of life, like comparing a college student to a kindergartener.
Third, women simply don't see sex as an achievement or something to be proud of. In fact, they're rather ashamed of themselves if they have a high n-count, because they're extremely aware that they're always the gatekeepers of sex, and a high n-count reflects nothing except that she has poor standards. They also often undercount their n-counts, because, "Oh, I was drunk, so it doesn't count. And then there was that other time, but it doesn't count, because it sucked." And so on and so forth. Remember, your n-count can only get higher, even if it's still zero. And hers will never get lower. Be thankful because a high n-count is generally good for your self-esteem as a male; it works in reverse for a female.
My personal experience
I remember about four years back when I met my fuck buddy, and we talked about our sexual history. I was so ashamed, because she was my n=3, while she was younger and already at n>20. She told me these wonderful stories about threesomes, hookups, swinging, all the ethnicities she "tried," all the locations of her daring sexcapades, orgies/parties, etc., and I'd feel so left out and inferior and useless. I kept comparing myself to her, and, when she was seeing more action than me in our open LTR, I became deeply contemptuous of her.
It wasn't until later that I fine-tuned my game and started seeing some REAL results (last week alone, I added 4 to my n-count, all Tinder hookups -- I was getting laid at the frequency of a girl) that I realized that I had it better. Fast forward 4 years, she's now 27, still alone, jaded with a thousand-cock stare, wrinkles starting to appear, putting on weight, etc., and, most sadly, scrambling around, dredging the bottom of the barrel for a beta provider before she looks too haggard for even the Betas to accept her, while I'm the leanest AND buffest I've ever been, and I'm having all the sex I can handle. I haven't masturbated in a super-long time. Right now, I don't even compare myself anymore -- I'm way beyond that. It's no longer an insecurity of mine, because I worked hard to raise my SMV and put myself in the field to meet women and close on them, and I've achieved everything in my sexual bucket list (quantity, quality, breadth of experiences), and I'm damn proud of it.
Always remember -- while girls get sex effortlessly, it's almost never what they really want. What they're after is commitment. And their high n-counts are something that they have to carry around as a badge of shame, as a reminder of what loose, standardless sluts they once were. It's something they have to make peace with, once the dust settles and the fun and games end, and they realize that their high n-counts are just evidence of their inability to secure commitment from a whole string of men who saw them as nothing but cum buckets. There's really no reason to envy a girl for her sex life, because she'll deal with the consequences of her debauchery come post-wall, where her slutty past will haunt her.
