Mmmmmh, biting is great! And blowing some air to the same place at the neck also. This can give perfect goosepimples to the partner. I like it to give and to get!
But take care near the orgasm because you might loose control. Then it is better to either not bite or have the mouth completely full. In this way the danger of hurting somebody is smaller.
