We are new here so sorry for diving right in on one of the biggest burning issues of modern life and I am going to write a long reply this time, just as it's a pet subject of mine and I'm bored 
Feel free to skip to the tl/dr bit if you can't be bothered to read it all.
(Incidentally, we have started a group for anyone wanting to explore their bi side a bit more, so go check that out if it's of interest, only just started but from tiny acorns etc....)
I guess everyone has their own slant on the definition, so I'll give *my* view but remember I'm not saying this is the same for everyone. [I'll mainly be referring to bi-males below, as we all know that bi-female play has become largely normalised on the scene and appears to carry none of the baggage or mental anguish although I'm sure that's not actually true in reality!]
1. I believe a vast majority of people are on the bisexual spectrum somewhere. Certainly I think a very high percentage of people on the swinging scene are (just from observation over the years) however if you asked people to self classify it would look instead like a tiny percentage. It's a hangover from swinging being synonymous with the painfully heterosexual pastime of "wife swapping" I think. In reality the scene is very different now, with varied participants - from the wife-swappers of yore, to soft play, cuckold, bdsm and all types of fetish and kink in between. And yet despite this shift in acceptance, so many think that being really honest about what they like will severely limit their play with others who are 'openly anti bi' or perceived to hold homophobic views as they will be seen by these individual as gay and ostracised. Some others hold those prejudices themselves and self-stigmatise without the help of anyone else. Others worry about their partners perception and like to introduce the concept gently... End result - most people hide or play down their actual preferences but for a multitude of reasons.
2. We are big advocates of just being honest on profiles. Elsewhere, we are inundated with guys who are listed as straight but are happy to shag us both, to the point where we start to wonder if they are so brazen about being dishonest around their sexuality, what other things are said that may not be quite true? And is claiming to be bi just a ruse to get access to the female?....as a result when we meet people outside the club environment (and therefore can 'pre vet' possible meets), we now have a policy of not meeting anyone knowingly listed as straight, and that can include couples too. A few guys have challenged us and said it's because they don't want to alienate some women who don't like bi-guys, but I take the view that if someone is bigoted enough to 'not like bi guys' then they are not someone I'd want to have sex with anyway so it can actually be a good filter. Plus, surely the purpose of a profile is to get to have sex with people who are really in tune with you so it can be a mind blowing experience? Pretending you are not into something you really do want can only possibly lead to a higher percentage of less satisfactory meets over time, so it seems counter intuitive to me.
3. What does 'Bi-Curious' mean? I'd see it as meaning you are open to trying same-sex play but are not sure if it's something you will actively seek out long-term. Now it may take a few experiences to really solidify your view, after all playing with different people can give very different experiences, so why decide after the first time? But I'd say anything much more than 3 or 4 times will be stretching the 'curious' definition a bit! In fact I sometimes find a profile with someone who is clinging onto the 'bi-curious' status despite many bi meets as a bit of a turn-off, as it starts to make you wonder why they don't want to admit it, and if *they* have a problem with bi guys/gals themselves or are trying to be all things to everyone just to improve their hit-rate!
4. There IS a distinction between 'real life' and 'swinging scene' which broadly relates to how much the bisexuality relates to physical or sexual attraction and can confuse some. Take me (male) for example - I walk down the street on a normal day and I barely register the existence of males, let along any that are supposed to be attractive. But I would find the opposite with women - I'd be aroused at curves, cleavage, showing leg, clothes, hair..... Not that I ever want another relationship in my life, but if I were forced at gunpoint, It would be with a female - I have a strong physical and emotional attraction to the opposite sex, which is why if I had to define myself in a vanilla 'real world' setting, I would say 'straight'. Sexually however, it's a different ball game. When things are getting hot and heavy then I find the idea of playing with a male - especially with women present - a huge turn on. I like the idea of not having restrictions or places that are off-limits, where everyone can play with eveyone else and yes, in a sexual setting I find a cock stupidly arousing, and as for anal - well I shattered that particular taboo more years ago than I care to remember! Sexually, from a play perspective I'd be hard pushed to choose a preference - I'm clearly bisexual and get turned on playing with both sexes equally. I only mention this as I suspect a lot of guys have the same internal dilemma of trying to categorise themselves for ALL situations, rather than accepting that what turns you on in a purely sexual setting may be different to what you gravitate towards in the rest of your life and they end up in some half-way house 'bi curious' category as a result.
5. We prefer to be open about being fully bi, as we have more chance of meeting the kind of people we are ideally looking for, and can scare some of the more ignorant people away. Bottom line though, is that for us 'bisexual' as a label is not telling the whole story, as in reality we would probably prefer to just be thought of as 'hedonists' - we are open minded to try new things and if it feels good, we keep going and if it doesn't we don't. There will be times when I'm really into the MF play side of things and really don't fancy any bi-play at all and times when I am so horny and I crave a good hard pounding myself or fancy losing myself for a while with our playmates regardless of gender. If it feels good, we do it - regardless of labels or anything else. We've had some amazing experiences and met some amazing people over the years, so have never personally found being 'bisexual' as a handicap and in many cases the openness improved meets. Some of our best and loveliest friends on the scene are straight, and some are the filthiest, most deviant bisexual pleasure-seekers on the planet. Variety is the spice of life, as they say! At the end of the day though 'Bi Curious' is not an orientation in itself - it's an indication of a direction you may be heading, and the ultimate destination should still be 'Straight' or 'Bisexual' eventually (and lets be honest, in most cases it will be bisexual).
So, If you made it this far, thanks for hanging in there....I mostly write one liners, honest!
too long;didn't read :
PEOPLE LIE and for a multitude of reasons, but they would probably have more fulfilling and mind blowing time if they didn't. Oh, and I'll call BS on any bi 'curious' guy who has entertained a cock on more than a handful of occasions
