General creepiness guideline: Take the older age, divide it by 2, add 7. So 13.5 + 7, is over 20 years old, so it may be a bit creepy.
Power imbalance. A 27 year old has a loooot more power in a relationship than the other one. They'll usually have more money, a good sense of self, more experience with dealing with people, and so on.
It can be okay! Stability, relationship experience, etc can be sexy and helpful. It can also mean you don't get to make your own decisions.
If you do, you're not going to have the same chance to grow on your own, find things out on your own, and you'll have a harder time learning who you are if you're always in the shadow of someone else. This can mean you waste less time doing stupid things (if he's clean, you're less likely to do drugs) but if he does stupid things, you'll get caught up in it.
So... depends, but probably too much.
A good rule of thumb - ask your friends what they think of him. If they all really approve, that's a good sign. If they aren't enthusiastic...
The age gap gets less important as you get older. My partner is 10 years younger than me, but we do okay. It's still true that I have more relationship experience than she does... so I know ways to lower stress between us, etc, which is good. But if I wanted to be a complete jerk in her life, she'd be in trouble. >.< (not that I like to even think about that, but it's true)1
