From a guy, my perfect?

1. go from kissing my mouth to sucking my nipples. Early on, sucking them as you like it, trains me.
2. Lightly tickle the balls with your nails.
3. When you go down, lick and tease the balls and the taint first.
4. Obviously provide that look for me, "This is going to be great."
5. Kiss and tease my sack, hickies w/o the marks are good but don't pull my balls into your mouth. This may be my issue, but it hurts.
6. Always initially lightly touch my shaft. You are not starting a lawnmower.
7. I personally don't like too much suction so slow & soft is great. Teeth are not necessary.
8. Deep throat is good but some of the best did not include that.
9. Continue to play with the balls, taint, and around, but not inside, my rear end. One caveat is I had one partner that could time the prostate massage as I started to ejaculate. If you did it before I start to come it becomes the overwhelming feeling and ruins it. For me, that is not good, but if you time it, wow.
10. Swallowing is not needed but not bad, if you stop hold and squeeze the shaft.
11. My head gets very sensitive after I come so focus on the shaft.
