Not so fantastic sex

Me and my bf are a long distance couple ( soon becoming a normal couple tho!) We have recently started to be sexually active but there's a bit of a problem. Neither of us is finding it particularly great. Don't get me wrong it's not not enjoyable. But it's not fantastic either. We have only had sex 8 times and we are each others first. Any tips? Comments? ...Edit: I love him to bits. We have the same sex drive. We are possibly still nervous. Some times plenty of foreplay but not always. We are so comfortable together, clothed and unclothed.
