If you just want to cum its much easier to use your hand. You can tighten or loosen your grip at just the right time, increase or shorten the stroke or stroke just as slow or fast as you want and prolong your climax so you cum at exactly the right moment. You have very little control over a pussy, its attached to a woman and her entire physical and psychological makeup. Even by itself a pussy is complex, there are the outer lips, the inner lips, the clitorus, the vaginal opening, the cervix, their wet when she's horny and the clear mucus turns to a creamy sticky slime and there's always a musk. Also when she's horny blood rushes to the tissues, the clit swells and the lips distend. When she cums there are a series of involuntary contractions that are some times visable around the anus and vaginal opening and can sometimes be felt by your penis or fingers. If your are a normal male heterosexual (not saying that our gay brothers are abnormal) the very appearence of a willing pussy and a willing woman will make your knees week and you heart thump and blood will rush to your penis and it will start to throb. About here is where the comfort you had in your hand is gone, you have to be careful not to cum just looking at a wet willing pussy, then when you put your cock in the feeling is warm, moist and maybe not as tight as your hand can be but better, intense. Now start to move but don't cum, you have to wait for her, you have to fight it, you have to sense where she's at, does she want to change position, does she want to manipulate her clit or does she want you to do it or not. All this is using mental and physical energy for both you and her and if either of you make a wrong move you will lose control and cum and the moment may pass for her and she may not be able to climax. You have to stay hard, if you start to go limp you have to work to keep it in or you will fall out and spoil it for both of you. But when she cums under your control, there is nothing like it in the world, nothing better, nothing.
