Traveling around the world with your boyfriend?

I know it's alright to travel around with your boyfriend as long as you can keep your purity. And I'll admit the enemy has tempted into sexual immorality when I'm with my partner. 
I was in church this morning and the Pastor's message hit me leaving me in deep thoughts. Should I continue my life of sin and travel with him around the world? Or wait for it until he gets married with me. 
We've both talked about it and he says he can control it and that he doesn't want to married just yet if he isn't ready in terms of being able to financial support me as my husband. 
I told him that wasn't the issue. I'm thinking he's scared of something else...
Anyway, anyone has any thoughts or comments to share?
