You probably don't want to hear this, but I too would say ditch the lube, especially if you want your gift to be meaningful. If you really want to get him a massage, then instead of giving him lube, give him a gift certificate.
If you really want to give him something meaningful, then give him something that shows how much your relationship means to him. I've gotten a more meaningful gift then that from a girl whom I was only with for a month and a half, and that says a ton.
Remember, it's never about how much you get him, but rather what you get him. Sometimes the simplest things make for the best presents. It all depends.
But know this: you'll have to live with how he interprets your presents for the rest of your time together. I guess the whole point is, be careful what you get him and make sure you don't ruin it.
And if you really want to be sincere about your gift, then don't ask a forum. He's not MY boyfriend, he's YOURS.
