What are some good songs to make love to?

So, my boyfriend and I are both joining the air force. He is going to the Citadel first so he will be a higher rank than me. We both are still virgins and plan on waiting till marriage. However, with him going to the Citadel he can't marry me till he gets out and that's in 4 years. I just want to make him a mixed tape bc that was how we started talking was over a playlist and talking about music. So i was wondering what were some good songs for military or to make love to. i want slow songs like Damien Rice. i want it to be for pionate love making instead of just "rough and dirty" and suggestions?
