What is the worst that will happen?
Well, I liked your idea. "I have a girlfriend". No labels.
Unfortunately, the next logical question out of their mouths will be "So that means you're gay, then?"
Back to square one....
I can always act like a politician.
Them: "So that means you're gay, then?"
Me: "It means I'm in a gay relationship."
Them: "How long have you known that you're gay?"
Me: "I've always been attracted to girls since middle/high school."
Something like that? Still honest but not quite labeling myself?
B), as much as you love this woman, and want to be with her forever, you never do know what'll happen. What if you now say that you're gay, then sometime down the road you and she split up and you end up with a guy? ...But then, I'm pretty cynical when it comes to relationships.
What if things changed down the road? Or if your gf died in an accident or from a serious illness. How would you explain to your family your dating with men again?
I would have to disagree with dating men is "easier and less dangerous". I am thinking of date rapes, abuses, or even VD if the man is a high risk.
I always think that honesty is the best policy so 'bisexual' gets my vote. Of course, I leave things up to you.
I dated a guy afterwards.....
I think you are worrying too much about what they will think. You are who you are and your sexuality should not change that. The only thing you might get is what I've always gotten. "Oh, your bi? That just means you are curious or undecided about what you are." The best thing you can do, is just be who you are and stop worrying about what others will think. If your family loves you, they will accept you no matter who or what you are.
Just to clarify It's not so much about worrying what they think of me, but more like one way probably would be a lot easier to deal with than another way.
I don't want to deal with 5 years of "You can still fall in love with a man. Why don't you meet Bob? Just try dating him for a couple of weeks!" where I could EASILY have them just sigh and accept it (if I said I was gay). My family is incredibly STUBBORN.
So that's why.
Isn't it odd that heterosexuals never even think about how to disclose their sexual orientation, or the impact it might have in various circumstances. That whole "dominant culture" thing.
