A genuine problem-am not satisfied sexually by my husband?

We are married for 3 years,n have a baby. We do it regularly,but its like i dnt enjoy it. Its more of an excercise for me than sumthing pleasurable. I am a very shy kind of a woman,never been in a relationship before. When we are doing it i close my eyes to avoid eye contact. Now i want him to force me to keep my eyes open.or experiment new things. I wana enjoy too. Wot to do,how to get rid of this shyness.
