Definitely!
Definitely try doggy style - it can be so sexual and erotic! Get on a bed (relatively firm) on your hands and knees, or bend down on your elbows with your bum sticking up in the air, and have him enter you from behind. To get him a bit more firm before entry, stroke his shaft with lube and pump your hands around it! He'll love it. Once he has entered you and you are both comfortable, he should begin usually thrusting. As you get more into the position, ask him to go harder and faster, and encourage him to thrust deeper by adjusting your body positions a bit to help him out. You will both benefit from this and be turned on. Allow him to fondle your breasts if you wish, or stabilize himself by having one hand on your hip and another fondling your bosoms. You can either do nothing with your hands, reach back and stimulate him, or reach around and pat his bum or hold onto it to guide him. He can also use his hand to insert a finger inside alongside the shaft to stimulate both of you. If this doesn't work and he really has trouble getting an erection, try flaccid entry, where you basically fold a non-erect penis into your vagina and hold it there during, say, a make-out session with your lover, encouraging him to experience being inside you. With this, use lots of lubricant on both of you, and don't have him thrust. He may even get hard inside of you, which is a truly incredible feeling.
