The OP is dealing with chronic loneliness and romantic rejection based on her own physical appearance and more importantly, based on personal, real experiences she's had. And quite frankly, if multiple young men are on here complaining about female expectations and how suicidal it makes them, I don't see why the OP shouldn't be allowed to ventilate her personal frustrations with male expectations.
Coming onto this thread to essentially blame her for making negative assumptions about men, attribute her problems to her "maybe it's your attitude" probably wouldn't fly if it was the other way around. It might not be consequential but I am a woman and if I went on one of the incel threads and commented, "maybe it's your attitude toward women that's making your life suck", I'm about 1000% percent sure I would either get the thread locked or receive a warning of some kind that I'm invalidating the OP's pain.
Also, the OP didn't say jack shit about being "entitled to a man's body." She is purely discussing her personal experiences of how she's perceived or treated as a potential romantic partner based on her size. I have no clue where this notion is coming from.
