Humidity reading of 50 too high?

ok so I always think we have a moisture problem in our house and it is summer and our house always seems too muggy so I have the humidifier going most of the time. So I noticed lately that it is reading at about 50 all the time. Is this too high and a sign of a moisture problem. It seems like our air conditioner is shooting out water. It is keeping the house cool but seems to always feel damp and not a dry cool.
