What things should a boyfriend do for his girlfriend?

Depends on the girl.

Well, what's she like? Work from there; if she is a girl who genuinely wants a good boyfriend and to be a good girlfriend then just be there for her, etc.

If you mean in a more adult way; then as this is in teen dating I have no interest in giving an answer.

By the way I do see the irony of that I answered a question that I may have no interest in answering. If this was a genuine question of being a good boyfriend then sorry about the above; but you understand.
