That's unlikely. If you were a guy they wouldn't be talking to you at all. Even less likely they'd do so with genuine interest. That is the experience most males have in such conferences. Few men get any kind of attention from anyone without putting in a lot of effort.

Having men lose interest in you after your fiancée is mentioned doesn't tell you anything about the likelihood of them seeing you only as a sexual object. Could just as well be a human object they want to love.

Take object out of your last sentence and I maybe can accept your point better..
