Maybe this is something that have been hidden deep inside of you and now that your at mid age you have the never to act out these feelings, and I dont believe that you havent felt this before, people dont just want to sleep with the opposite sex unless that are either gay or by sexual. Or maybe your trying to enter into the porn business.

It's been known to happen that someone who has thought of themself as completely straight (or completely gay) suddenly wants to jump the fence with a particular person. It's called a sexual attraction. If you just wanted to do something different you could take up sky diving or book a trip to Mongolia. You are attracted to a particular man. Now, do you want to do anything about it?

you have a good point.

maybe it's time to face the fact that I might be bisexual. hmmm, seeing it all written down makes me think I need to start addressing this. Life is so funny.

Maybe you are bisexual. Not that there's anything wrong with that! I have had bisexual leanings since I was in my early thirties. I like women better, but some guys can really turn me on sexually. Not so much the person, but more the act itself.
