You seem to have a handle on what a man likes from the pointed questions you asked. Here is "my" take...
"For men, what is the most sensitive area of the penis that you like sucked/licked; shaft, head, under the head, scrotum or around the scrotum?"
For me it is the head and the bottom of the shaft leading up to the head.
"What other areas of the body are very sensitive for you?"
Ears, nipples, and the area between my balls and my anus.
"Would you rather have a back massage, full body massage, foot massage..etc?"
My wife gave me a full body massage one time by oiling me down and rubbing her breasts all over me...talk about a HUGE turn on.
"Do you like to lie on your back with the woman sitting on your face giving her oral or would you rather be on your knees?"
I like for her to lay on her back and as close to the edge of the bed as possible. I then kneel on the floor with her legs bent over my back. I find this gives me the greatest penetration and breathing room.
"Do you like women to run their fingers thru your hair and lick your ears and earlobes?"
"Give me ideas for my lovemaking sessions."
I personally would like to see my wife "play" with herself. My ultimate goal is to watch her spank the monkey. Lay an old plastic shower curtain on the bed and cover it with a sheet and then oil each other down. Don't forget to please as many of the five senses as you can.
