Try this: It worked for me both before E.D. and after.
In man-on-top position it is easiest to describe (and to accomplish)
Put your penis on your woman's belly and move your body fore and aft along her body so that your penis glides up and down her pubic mound.
Moving your hips down (both towards her feet and down towards the bed) let your penis tip feel for her vaginal opening (if she is wet, you should be able to detect it easily).
When your glans (penis tip) is in line with her vaginal opening her body should be supporting your penis as long as you don't move down too far.
If she is aroused, her labia should be swollen and wet enough that they will open easily to allow your penis tip to enter.
If you fall out, simply raise up your hips, move up along her body and repeat the steps outlined above.
Edited to add:
Of course, if you point in strange directions, you just choose a position (that takes advantage of your new penile direction/angle) and maneuver your hips to point your penis where it needs to go. Not unlike aiming a punt gun. (Look it up - a most interesting mode of hunting waterfowl back in the day).
