Enjoying sex

So question, I've only had sex three times but I haven't like really enjoyed it pleasurably. Mentally it's great. Like I love the act but I'm wondering if there's like something or some way I should move my body when a guy is inside of me to help make it more pleasurable? I feel like I might not be doing it correctly in order to help my body feel it correctly. Or maybe I'm just still quite new and I have to get used to the feeling of a penis inside of me lol
