Ever dated two guys at once?

I’m seeing two guys, and no I’m not in a relationship with either one, yet. But I know that they’re both going to want me to commit soonish but I don’t know which one to choose. I’m scared I let go of one only to regret it and not be able to get him back if it doesn’t work out with the one I chose.

Anyone been in a similar situation? What should I do?
