Am I doing something wrong, or am I even pleasing her, or is this just common for some females??? Any input would be gratefully appreciated.

Making noise during sex is a very personal decision and is not related to the sex of the individual. Some people find that making noise arouses them and makes sex better, while others find it a distraction so that it detracts from sex. There's also an issue with what the noise is. Some people like to talk "dirty" while others find such talk offensive.

What you have to do is make some noise outside of the bedroom and have a talk with your girlfriend. Though your main concern is about making noise, the key issue is whether or not she is being sexually satisfied. If she's being quiet because she's not aroused and not reaching a climax, then you have a problem that must be dealt with. But if she is satisfied as a result of your lovemaking but tells you that making noise would be a distraction, then you have nothing to worry about and should just drop the issue. Of course if your noise-making bothers her, then the situation is a bit more complicated, especially if you need to make noise in order to become fully aroused. If your noise-making bothers her, then you'll have to see if you can reach some type of compromise.
