I'm new to dating and appreciate input from those who are single for a longer time.
I'm widowed <1 year after 41+ yr marriage. I'm exploring who I am as a mature single woman. I need time and experiences to decide what I want from dating.

It is my hope to date more than one man at a time, if I should get lucky enough to have the opportunity. People have different interests, like to go to different kinds of places, have different kinds of conversations. There were experiences that I missed out on during my marriage because they didn't interest my husband. I'm single now. And I'm not looking for a permanent mate, so I don't want to make those compromises.

Am I being unrealistic to think that men will accept a non exclusive relationship?
Sex is possibly the biggest barrier. It would be unsafe and unfair to have more than one sexual relationship at a time. If I set that boundary on one person, that could be a deal breaker and make the whole question moot anyway.
