Girl talking sh*t behind my back

So today I was talking to a guy-friend and he mentioned he’d had a very weird conversation with a girl he met the other day. She apparently knew me and they started talking about me. My friend mentioned I was pretty and had an awesome body, to which the girl made a “meh” face and said “yeah, kind of”. For some reason unknown to me (‘cause he should’ve just dropped the subject and shut the f*ck up🤦🏻‍♀️) he felt the need to insist that I was hot and had a bunch of guys who liked me. To this she answered “Uh, not really. She’s got a reputation for being a prude, and guys don’t like that.” He just stared and she proceded to tell him that my ex (which I actually dumped a little more than a year ago) had dumped me for not “giving him any”, and “starving him sexually” 🙄. She concluded that I thought I was better than anyone and that’s why I was still a virgin (which I’m actually not 🤷🏻‍♀️). Finally, she added that my current boyfriend must be really desperate to actually stick with me, and will surely dump me as well or be unfaithful once he realizes I’m “not worth the blue balls” (which he really doesn’t have because he’s let me know he’s VERY satisfied with my performance, loves every single part of my body, and even told me I’ve done things to him that he hadn’t thought possible IRL 😅).

Although I won’t let this get under my skin I still feel nauseated by the fact

that this grown-ass woman would enjoy speaking like this about me. She actually considers the fact that I don’t publicly announce my sexual experiences as equivalent to being arrogant. WTF???? But at the same time, I can’t help but laugh ‘cause that means I’m really good at keeping all the naughty things I’ve done (and still do) out of the public eye 😝

Has any of you gone through this before?
