Well, you're in the smaller side of average, so you'd be suited to pretty much every style.
Some thoughts I've had on my personal messiah, 'cowgirl':
-Girls get to control when they're on top, and change to angle to suit them.
-Guys are able to breathe since their muscles aren't being used and hence not seizing up their body, whichs helps 'control'.
-Good penetration and, potential G-spot stimulation, it also spares up your hands for some 'playing'.
BUT, some girls like being in a slightly more indominant position until they get really comfortable in a relationship.
So, just ask them what they like, until you think they're fine with being dominant, and girls enjoy being dominant occasionally.
