There is nothing in the world sexually better than those first few seconds after plunging into a tight wet pussy. If you want to be asexual go for it. I 'll take the pussy.
I think both are just as important as the other, i also prefer masturbation rather that random sex as i hold that connection between two people very special
With experience your own hands can do a better job of pleasing your cock than another person (pussy, mouth, or hands) could ever do. Practice, practice, practice, practice, practice, and practice some more! Here is a link to a pic of my wife helping me do it: http://www.imasturbate.org/modules....ame=Gallery&file=index&include=view_photo.php
