First off, I confess to not having read all posts because I'm online on my phone, and It's agonizingly slow tonight. I'll make sure I read them all later though, pinky promice :tongue:
As for the threesome arguement, I've always found that fascinating! I do not believe there's 'one right answer' to the question 'why?' though, but it's interesting to ponder over.
I always figured an explanation why lesbian sex and mff threesomes were so loved by straight guys (and lots of gay men and straight/bi/lesbian ladies too) is that there has always been somewhat of a focus on the female body - be it in the media, art.. Anything. The round shapes of a female body are often seen as sexy, an art in itself. Something to look at and admire. The male body, however seems to be admired for other reasons by the mass; strength, power, abilities. It is seen as pretty because of it's purpose - not purely and solely for the aesthetics. While a female body in general can be beatiful by itself, the male body is often looked upon for it's qualities. Like one would have to account for even admiring it. I hope this makes any sense!
I'm not saying these are my personal views and I could have interpreted it completely wrong. But hypotheticly, it could explain why lesbian and mff sex is looked upon as sexy instead of posing a thread (be it to ones sexuallity, relationship or the chance of finding a partner in general): the enjoyment and adoration of anything female is nearly considered 'normal' because it doesn't need explanation or haveto be sexual. It has been excepted to be beautifull either way, so doesn't nescesairy have to be linked to partnership and 'finding a mate. Maybe you could say It's 'not sex'-sex. Think about it: while 'gay' discribes both male and female same-sex sexuality, we found it nescesairy to lovingly find a specific name for female same-sex sexuality (lesbian), as if it would be different from the general idea of what is gay. To pretty it up, perhaps.
Then gay sex and even mmf threesomes could pose a thread, seeing the male physicque is loved for it's abillities and qualities. Seeing those can obviously vary, but it's a lot more specific. Like a large penis for an example: directly linked to sexuality! It suddenly becomes a lot more personal, because it would actually say something about a personal preference (the preferance of said specific feature, not nescesarily the preferance of men).
Eventhough that would sound like a lame excuse and a bit crazy even (and it can still be), it could be why anything involving more then one guy seems to be less excepted: It's merely prudeness, because it would involve us reflecting on our sexual preferances.. Which simply still aparanty 'not done'. We're afraid of our society thinking we don't fit the norm, we're affraid of beeing judged. (a norm we would find out to be anything but consistant WOULD we actually be open and honest about it - we peoplez are silly creatures, are we not?).
That all beeing said, I personally think the male body is just as much a piece of art as the female body. Human anatomy is just beatifull for both it's simplicity and complexities. Sadly, these views seem not to be commonly accepted in the purest form.
As far as threesomes go, I've had my fair share so to say. I've noticed mff usually doesn't work for me: for me personally, sex with another lady is a totally different experiece than sex with a man. And eventhough I love both, I mostly prefer them by itself. I tend to feel I can either focus on having sex with the lady OR the guy.. If I try both, it seems I lose that focus for either. There have been exceptions where it felt differently, where it seemed to just 'click'. But generally, they're not my preferance.
In my experience mmf threesomes with bi-guys are a lot 'easier', seeing the experience of both sexual partners for me is the same (in it's basics I think of my experiences with ladies as primarily erotic, sex with a man is more about lust). I love bi(curious) guys personally, because in a threesome I prefer it actually beeing sex among three people, rather than two people having sex with one. And ofcourse there are plenty of exceptions with this too, these kinds of threesomes for me tend to be less 'complicated' as far as dividing my attention goes, or atleast I don't catch myself worrying about it... For me is a lot more enjoyable when you feel free to do whatever and just totally give in to the moment.
Gay sex between two men alone, I find just as sexy and fascinating as between two ladies.. Perhaps even more! The fact that I can't play along 'cuz of the lack of penis only adds to the mystery of it. I love watching gayporn because of that mystery. Lesbian porn on the other hand, not so much.
All in all, I think the general idea of mff and lesbian sex are more often generally excepted, because it isn't accepted to question that statement. It feels 'safer' not to, because the time we live in is still a lot more prudish than we'd like to believe. We're still a bit weary about actually thinking past the one m/f sexual position we have been thought is the most 'normal' or 'right', and embracing that we primarly are; sexual beeings. And that sexuality doesn't have any boundries in itself but the ones we create.
(I know I must have repeated myself over and over, perhaps only talked pure nonsence. But I'm too drunk to care. I wouldn't rule out the possibility of me beeing very ashamed in the morning, though.) :tongue: :biggrin1:
