A guy can only be a good lover if he has practice with people who tell them what works for them. Did you ask why? The details of what she does/doesn't like?
My GF's and I have discussed how we all like different things. Some like the jackhammer, some hate it. Some like the romantic, passionate approach, some think its cheesy and a turnoff. And, then, there's the connection thing. Eye contact, etc.
