When or how did you realise you were bi?

I was 21, 2 weeks away from getting married. My fiance was shopping for wedding stuff with her mom. I was bored and snuck out to an adult arcade a mile down the road. I went into the back room where there were several video booths. I went into one, sat down, dropped in the coins and started an x-rated video.I'd never been in one of these video booths before and had no idea what to expect.

I noticed a waist-high 4" hole in the wall that opened into an adjoining booth. I could tell by the light and shadows that there was someone in the next booth. It seemed weird to me, but not alarming, so I ignored it and continued to watch the video.

As the video proceeded, I got horny and hard. Before long, I unzipped my jeans, took out my cock and started to whack-off. I looked down, surprised to see an erect cock sticking through the hole from the other booth. I'd never seen another erect cock (in person), let alone one this close to my bare, hard dick. I felt woozy and my pulse quicked. I was turned-on like I never felt before. The cock was big, thick and beautiful.

Something clicked in my lizard brain and I was aroused unlike ever before. Overcome with lust, I dropped to my knees and took the cock in my mouth. Before I knew it, I was sucking dick like my life depended on it. Meanwhile, I grabbed my dick and started pounding away on myself. Whithin a minute or two, he came, then I came. WOW! My brain was on overload. I vascillated between shame and excitement. A whole new world had opened-up for me.

It took me a few months after my wedding before I revisited an adult arcade. As time progressed, I went more often. It took a few years before I let someone fuck my ass, but it did happen willingly.

It never affected my attraction to my wife (I love pussy), but every once in awhile, I just need a dick. That's how I realized I was bi-sexual.
 
I maybe on the wrong thread here as i have never considered myself as bisexual, i love the female form too much especially nice jean clad figures. I am a long term, caged cuck husband and have always ensured that i steer her away from any potencial lovers who admit being bi.

My long term best friend gets on extremely well with my wife having fucked her in several threesomes, on one of these occasions he touched my bare ass, that made the hairs on the back of my neck stand up ...ugg. He has i know told my wife he is bi curious and we know he is a secret cross dresser.

My cuckoldress who has over the years, collared and caged me permanently and semi feminised me,

A few months back, she asked me if i was Bi, or curious, i said NO. This was followed by i always thought you might be, youve always worn jeans on the tight side and from your mannerisms sometimes, and your love of wearing female clothes. It wouldnt bother if you were, i just thought i would ask.

I replied, it was you that made me into a wearer of female clothing not me.

My mate on a rare escape from his wife asked if he could come have a few drinks and stay over, we agreed.

On the evening after showering my cuckoldress changed my day collar for my heavy BDSM one and allocated me very tight female jeans never before allocated to wear infront of anyone and knickers and a cage as usual. It was a shame i wasnt allocated suspenders.

During the evening we all got rather ...... and it was she that made admissions to him about her lovers, that shocked me but did turn me on mentally, then soon after she simply said, i am off to bed i will leave you boys to it. Not an unusual saying for her.

As soon as she had gone, he asked me if i was wearing suspenders, no i wasnt, then he dropped his jeans showing he was. ...... i soon found myself on my knees sucking his cock.

The following day i remembered as i lay next to my wife and thought.....i actually quite enjoyed that....

He didnt cum and i dont know why it stopped, but he has said since i was rather good at it and next time he will repay me.....

He also said he loves my ass in female jeans and always has and wants to be able to feel my jean clad ass when he wants especially whilst he is on his knees.

Then the killer: he would like to do this infront of my cuckoldress...at the back of my mind i just wonder.....
 
I was in 8th grade when I started to get curious, but really it was in high school when I realized I was paying more attention to the guys in porn than girls. My senior year I finally decided to try sucking a guys cock and met someone on craigslist that had a massive 8 inch cock. I was nervous, but I liked it. I think within about a year i finally got fucked by a guy from craigslist and I kinda new that was the direction I was going in. After college I would exclusively look at gay porn. I still look at straight porn, but only if its cuck or milf porn, it's still like 75% gay porn. I go through phases I guess where I go back and forth.
 
On one of our first visits to what became "our" club, my wife was sucking dicks in a row.
She allowed one of these men to cum in her mouth.
Then she crawled to me and cum kissed me. In front of these men!!!

I wrote a journal of our happenings which she corrected, complemented and provided with her comments.
That included hot pillow talks and email exchanges.

Regarding this first cum kiss, her comment was:
‘We chose for this lifestyle. So it is not mine alone but yours too. That cum kiss was meant for that.’

She later complemented:
‘I think you should just get used to the taste.’ (A hint?)
and
‘It makes me horny when I crawl towards you and then show those men that you are my cuckold. Then they feel freer to engage with me.’
 
I had several male-male experiences over the years, reaching a pause during my freshman year in college. In that interval, I never considered the experiences as bisexual, or homosexual, just opportunistic, perhaps taboo - neither did I label or categorize myself as bisexual or homosexual.

In my late thirties, I resumed bisexual experiences, first with another couple, a Craig's List hookup. I've never really looked back, but I still consider myself more pansexual, if I were forced to adopt a label.

Both my wife and I really, really enjoy group sex, which often includes bisexual contact between the participants, both male, and female. Sometimes it is reluctant, curious, as an inexperienced participant explores opportunity, other times enthusiastic, performative. Always hot.

We currently live in a poly situation, my wife, me, and three other men, two of them I'd categorize as her lovers, one a live-in fuck buddy we all share. The opportunity is inbuilt for the male part of our group.
Your beginnings sound a lot like mine
