Hi sweetheart. First of all, don’t get discouraged and you are not broken. You are only 19 and you actually are most likely fine, and most likely your partners up until this point have either not known a woman’s body or been able to allow you to get in the right headspace to achieve orgasm.
Only 5 percent of women never orgasm at all, and my guess is most of them are non-masturbating bible thumpers who have husbands that suck in bed. The number that physically cannot achieve orgasm no matter what is probably around 1%, is my guess.
Also, only 25 percent orgasm during vaginal intercourse “consistently”, so it’s not like you are alone. Now that last number may seem out of thin air, but it is actually based on a comprehensive analysis of dozens of studies over 80 years.
In my experience, no women came with me until I fucking figured out a woman’s anatomy and unfortunately most guys never learn that, so you may just be having sex with idiots, like most women. I’d be willing to bet that with the right guy, you will probably cum.
Now if you are one of the people that cannot orgasm at all, ever, with toys by yourself or anything, you still are not broken. You can still enjoy sex just as much and it can be mind boggling.
There is a post called “There Is Nothing Wrong With You”, where I cover this specific topic. I think you should read it, because it will shed some light on what I believe is a misconception that an orgasm equates to good sex. You can still have good sex and not cum.
