I think it's a very personal question and I wouldn't be too thrilled if someone came out and asked me unless of course, it was the topic of conversation to begin with.
Absolutely no one my partner and my family knows my sexual orientation, except my partners cousin. She is bisexual and much less judgmental than the rest of our families. I'm fairly secretive about it because I'm currently with a guy so no one thinks to question it. Both sides of our family are very old fashion and my side has stuck with their religious beliefs.
I have had a few short relationships with females but never anything serious. I just never found a girl who was worth it to me.
My partner and friends are aware of my sexuality though.
