Can ual orientation change at 40?

Yes, you control who you are. No one can tell you who you are. If you want to be with a woman, experiment a bit. BUT, do not hurt the woman you are experimenting with. It would be easier if you had a small fling with one quickly just to try out. No harm no foul. If you enjoy it, then continue. By the way, if you have any experiences feel free to video tape and send to me :) Kidding (Kind of) Lol.
