Have you ever had a bi experience and if not would ...

I never have, but if I had the chance I totally would.  I mean, I think I would need to be drinking in order to have the guts to get started, but I think it would be fun. Why not?

yes i've had one, and i think it's worth it to try it.  how else will you know whether or not you like something?

Yes, I have.  And so have most people, according to research.  Our society is the only society in all of human history to come up with this idea of "sexual orientation."  I don't think it's a very helpful idea.  Even in societies that damned homosexual actions, they thought of it like other crimes, that anyone was likely to commit it.  Like stealing, you don't look around you and classify people as thieves and nonthieves.  Even if a person has never stolen in their life, you accept the possibility as very real that they might steal in the future.  Even if they have stolen before, you can easily accept they may never steal again.  Obviously, we have realized as a society that demonizing homosexual activity is pointless and cruel.  Our next step will be to realize that every single human being alive has homosexual fantasies and desires.  They may have so successfully lied to themselves that they can't even admit it, but it is there, or would be in the right circumstances. Same-sex experimentation is especially prevalent in young adolescents (11-15 or so) and can be a very troubling and nearly traumatic experience thanks to the way our society mishandles sexuality.  It should be an enjoyable experience and a fun way to bond with friends, exploring new territory together.  But thanks to this idea of "orientation", everyone gets scared that they might be setting in stone the rest of their entire life, wiping out countless possibilities, etc.

Throw away the idea.  Give it a try.  Stop thinking of people in terms of gay or straight, and assume everyone is bisexual.  You will be closer to the truth and you will find yourself a more relaxed and kinder person for it.  And if you have an opportunity and would not be breaking a vow to anyone, feel free to experiment.  It will not "lock you in" to anything.

Note:  This does not eliminate or in any way change a promise of monogamy.  Cheating is cheating.  Cheating is bad not because it is sex, but because it is deception.  If you make a vow to a person and break it, it proves a great deal about how much you value that person and vow.

I tried to deny my feminine side but a few years ago I met another married man who was also bi-curious and the result has been a long term affair which we both enjoy immensely. I am safe and secure in this relationship but what worries me is that my needs for bisex have become so great I wonder what would happen if this relationship ends. So, if you become bisexual please understand it can be psycially and emotionally addictive. It seems to me that bisexual women are readily accepted but men (and especially those with a femnine side) are not. I wonder if this will change over time.

You mentioned "having the guts to get started" and I had the same problem which I solved by having seeveral drinks prior to my first experience. I'm not much of a drinker and I'm not suggestiong anyone become one but it did remove most of the inhibitions I know I would have normally had. I was very relaxed and things went very well and when a man tells you he doesn't believe it was your first time ... well, you'll find out how good that feels if you do try it.  

I have had a bi experience and it made me realize what I know today about myself. I like men. Women are fun to play around with every once in a while but I could never be with a girl forever.

I think you need to have one to determine yourself and your interaction with others and theres nothing wrong with that.
