Like I said earlier it's the hypocrisy and double standard when it comes to judging men and women in these situations that truly annoys me.
Well, I think we're annoyed by the same thing, but in different areas. I'm annoyed at the (new to me) sentiment that having a preference (no, I don't want to date a trans individual) is somehow shaming trans people. I personally think that's ridiculous, I don't want to date gay men either, so I suppose I'm shaming them for being gay too? I just find that to be a ridiculous position and frankly, filled with hypocrisy. I suspect that same poster would feel entirely justified in "nexting" a man who she found out was a convicted felon; not because he is a bad person, but because they just don't want to date a felon. I might even think that's silly, but I fully support their right to choose a partner on ANY criteria they want. Don't want to date black men, or nerds with glasses, or bald men? Fine, fine and fine.
And, as I've said several times, the double standard you're seeing, yes, it's certainly there. But it's there for a reason! It's not there because "society hates women", it's there because having a threesome says 2 totally different for men and women. A man who has a threesome with 2 women is demonstrating value, he's so "hot" that he can get women to agree to share him. It's only the highest of high value men who can have that experience; it's extremely difficult to get (especially, as we're discussing in this thread, when younger) and highly desired by, at least in my circles, nearly every man I knew. Couple difficulty in obtaining with a highly desired item, and you have something that's "high value".
Now, look at it from the other perspective, do most women want to have gangbangs with a few guys? IDK, but I've never heard a woman ask/suggest/want something like that in bed. Maybe a lot do, let's just say "yes" for the sake of discussion (although, honestly, I don't think that's the answer). But what about difficulty? Is it hard for a typical woman to find a few guys to have sex with her? Well, simply put, no, it's not. My wife could have 2+ guys here before the sun came up with a few pictures on any dating site and "NSA, but only if you bring a friend". No difficulty at all in obtaining it, and not as desired (IMHO) by most women. It no longer displays value because it's not "personally desired" and it's easy to get.
It's a double standard, yes, but it's a double standard rooted in biological and sexual reality. The best (non-sexual) example I can think of here is being overweight. 1000 years ago, being overweight was a sign of wealth/status. Because it was so difficult to get enough food (and leisure time), being overweight was a sign to the world that you are "high value". Now, of course, the situation has changed, food is so easily obtainable that the "value display" today is being thin, showing your value via self-control and eating healthy. A thin person 1000 years ago or a heavy person today could look at this and say "not fair". But, much like the example between men and women above, "not fair" doesn't matter. Reality is, being heavy today says something very different about you than it did 1000 years ago. In fact, today, it says the opposite thing, the wealthier you are, the more likely you are to be thin/in shape! Which, if you examine it, is exactly what we're discussing between men and women here, what for men is a mark of being "in shape" for women is the complete opposite.
