What opened your bi side?

It started for me during high school years. My first was with my close friend during a sleepover. We were horny from talking about girls while lying in bed together. We could see the bulges in our pyjamas in the dark and so challenged each other about who is bigger. Soon our erections were out and before we knew it, we were holding each other for the first time. It was thrilling to do something so forbidden, but it was an amazing feeling to hold someone else's dick for the first time.

It went on from there to years of exploration and naked fun whenever we get an opportunity (rarely), although we have pretty much exclusively played with each other.
 
My bi side started with dirty talk with my ex while we both sucked her dildo or her or my fingers together after it had been in her pussy, talking about sucking and tasting her on another man.
Few years after in a MFMF with a married couple the husband asked to suck me, which was the first getting sucked by a man. That eventually led to me ex wanting to see me top the other.
More recently was my first time sucking a man in a MMF threesome with a different married couple because his wife really wanted see us sucking each other.
So I would say sexually open minded horny women helped open up my bi side :imp:
 
I’m Top/vers. Like the rawness of male sex. No cuddling or long talks after fucking….
Like I wrote above, we meet to fuck. Do’s and don’ts are negotiated beforehand.
Had my best blowjobs from guys.
Totally agree with this but most guys I speak with really just want to cuddle for some reason....
 
I used to think it started when other guys years ago kept grabbing and noticing others' junks, one was particularly interested in mine. After graduated, I found one of my male friends hot and he was kind of exception among many girls I fancied. Then, what really opened my bi side, was reading manga stories, checking bands like Placebo, Tatu or Jane's Addiction, and just pure rebellion. I was not satisfied with my female crushes then too and needed men around me more.
 
Started out with curiosity from various types of play and overwhelming horniness. Was in denial about being "actually bi" and thought I was just super horny and using guys to have sex more often. Then I was hanging out with my gay friend who was draining my cock and he turned the tables, pulled my legs up, ate me out, stretched me wide, and bred me on his living room floor. I let go of those misconceptions, lol. Hard to pretend you're "straight but just horny" when you're begging for cock and jerking off all night afterwards because you can feel your friend's load leaking out of your ass...
