Yes, older people are way more homophobic, even sometimes with female bisexuality.
I have a buddy who knows many men in the sex industry. He said that all men are pretty much bisexual, no matter if they're "straight" or not. Being bisexual just comes with the territory as a male sex worker.
Some tough biker dude admitted to me that he wanted his woman to be with a well-hung man. I've had tons of straight dudes compliment my Big Dick. It's definitely on their minds, no matter how much they like pussy.
I do love watching two women make love. It's just so gorgeous. But my bisexual side is more about competition/jealousy. At any rate, I still have bisexual desires at times, even if it's not penetrative or oral sex with a man. I just like looking a well-hung stud without clothes. I like to see men jack-off sometimes. That can be exciting.
Enjoy what you enjoy. Don't let society and taboos get in the way.
