Yea, it's OK to call a guy Babe. Women call me Babe all the time. They whistle and cat call all the time, but I'm used to it. That's just the way it is when your HOT like me. I just hate being called Candy Pants though. I don't think girls should call guys Candy Pants. Not in public any way. In private they can call me anything they like. I had one chick calling me her bigg-o muff monster. I liked that one. Too bad I had to kick her to the curb for that tooth paste model. WOW! What a smile she had. Til she went over the handle bars of my dirt bike, that is. I dumped her at the hospitial. For the head nurse. She really wasn't the head nurse, that's just what I called her. In private, mind you. Yea, it's OK to call a guy Babe. I guess.

Yes you can. My girlfriend calls mebabe andi call her baby. Because she's my baby

Yes, you can call a guy babe, but as long as you are his girlfriend.
Hope this helps
