tummy vs back?

I know the benefits of tummy time. My question is a little odd. At least to me it is. Ds is 3 months, since the day he was born he preferred to be on his tummy. If you put them on his back he's happy for maybe 10 minutes and then wants to roll back over. So should I be making him stay on his back more? It's so bad that even to get him to sleep I have to let him fall asleep on his tummy and then roll him over.
