Is that an automatic deal breaker?

Imo,
There are no bi-men or women. They are homosexual. There just playing both sides of the field.

Not if your Bi...hehehe
Welcome and good luck...

Not for everyone.
Once you start removing the consequences to sex, or purpose from, remove its taboo nature, it simply becomes just a different way to obtain pleasure.

A lot of people aren't going to hold going bi against them anymore than someone that shoots up heroin is going to begrudge a crackhead, as long as everyone's getting a steady supply of what they want.

Mmmm bi guys are hot

Hi.

Heck no...bi women are hot and always up for a 3way...lol

Hard to find true love

It is for me, but that's because I only like women.

I've had relationships with bi women though, and that was no problem.

When it comes down to it, whether the other person is hetero or bi or gay or some other label, if they commit to you and honor their commitment, it wont matter what label may apply.

But if you're bi, and expect that that means your mate has to put up with you screwing around with the other half of your interests, good luck.

It is an absolute deal breaker to me.
And it's amazing (shocking actually) to see how many guys these days are bi. And that's the ones who openly say so, there's probably a whole lot more who are but don't publicly state it in their profiles.

It's one thing sitting on the settee watching a movie and my guy's drooling over let's say Taylor Swift.
It's another thing us sitting on the settee, me saying "Hmm... I'd like to sleep with Sam Heughan!" and he goes "Me too!!"
UGGGHH!!!
