1) Maybe he's shy, not every Brit is forward thinking, and some like to let the women do the moves, that way the guy knows he is not overstepping the line.
2) Depends how he is phoning, not everyone knows the cheap ways of doing so, he could be paying 400 pesos a minute!!!
As you say, early days, and you are probably both being cautious.
PS. If you want a loving trusting relationship with him, you need to be telling him this not us
