I have found my sexuality to be fluid. While I have always had an attraction towards some men I was able to shelf it because I was getting my sexual needs met with women. And let’s face it, in the days when I was younger our culture wasn’t as excepting of the gay lifestyle. In these recent years I have found that since I am feeding into being with men more and more it has taken much more of a center stage in my life.
I knew I was bisexual in my 30’s. I was married (still am) and decided not to stray on my marriage. 35 years later my wife says she is done with sex so I decided it was time to explore my other side….very glad I did. So to answer your question, not for me, just took the right circumstances for my bi side to emerge.
