It can be (if you aren't exclusive with anyone), especially if you tend to over-analyze or get too attached to guys you date. If you have more options, you feel more relaxed about it. Not as worried about whether a guy texts/calls you back fast enough, not worrying as much over when he'll ask you out, if you said the right thing, etc. and that kind of stuff.
It's not good for me though, because I'm already almost too relaxed and I just won't make a good connection with anyone if I'm dating multiple people at the same time. I have to be focused on one person at a time.1
