Of course it is good. Too many people are afraid to talk to their partner and let them really know what their turn ons and turn offs are. People need to have an open line of communication with their sexual partner this way everything is on the table and they sex can only get better. Good sex= Great times!!!!!!!!!!! Don't people want to give the other person what they need? Talk to them. Mind blowing sex is always the best!
It's always better to watch the other person have a body rocking orgasm. Then you know you are doing things right. Body language tells it all.
