Like others have said, it totally depends on the rooster. I finally have a Barred Rock rooster who is very good with the ladies and good with me. I am like you, I really didn't need one but he was so good with them that I just couldn't part with him.
Just a little bit of advice: it is a little jarring to see them mount the hens the first few times, it was unsettling because of the way they grab on and it just looks all kinds of wrong lol. Once you get past that, and the rooster gets smoother with time, it is just all completely normal now. The hens all love him and roost next to him, so he must be doing something right lol. Good luck.
