FOR THE MOST PART, yr just seeing (1) raw statistics and (2) opportunism.
#1, raw statistics:
Most men in yr demographic are in relationships.
More importantly, if you are in a certain "league" -- you know what I mean, let's keep it real here -- then, ALMOST ALL men in yr demographic who are in that league, and whom you would even give the time of day, and who would even bother approaching you, will be in relationships.
So, even if you are actually being approached by a completely random set of men from yr demographic... yeah.
The two most important factors determining whether a man will approach you are (a) you're there, (b) you're available (for conversation, I mean).
If you hang out around men a lot, then, there you go.
If yr in an environment with men who tend to be in relationships -- e. g., you work in some professional field with established men -- then... guess what. LOL
Okay. So, those two things will account for MOST of what yr seeing, here.
But, beyond that, I'd say there are two more things thata re possible.
#1, you may have a DISTINCTIVE look.
When men want to stray, one of the most important things they look for is VARIETY.
Men DO NOT cheat with women who look exactly like their current partner, pretty much ever. Ever. Nope.
So, if you have a look that's somehow "different" or "unique" or "exotic", then, by definition, that will make you more attractive as the target of an affair.
I have a girlfriend who does modeling for some local corsetieres. She's very busty, somewhat overweight (like most corset models), has piercings, and dyes her hair weird neon colors. Long story short, she gets approached by married and attached men ALL THE FREAKIN' TIME.
I mean, she's cute, and smart as a whip, and she's a great conversationalist, but it's pretty clear that her "exotic" look is a big part of the draw there.
So, if there's anything "different" about yr look, that would explain it.
#2, you may just exude sexuality.
They've done studies on this. Some women literally just carry themselves -- and walk, and move, etc. -- in ways that are more overtly sexual than others.
This kind of thing actually correlates pretty darn well to sociosexuality, too. In other words, if guys are guessing whether a woman's down to fuck, based on how she moves... their odds are a lot better than random guessing!
But... not perfect odds, of course.
Mb you just move really sensually and don't know it?
