Can you give me a list of book titles on male assertive behaviour please?

Hello boosan52-ga

As robertskelton points out in his comment, books on assertiveness
that target one sex, target the female sex.  After extensive searching
of both the Web and Amazon and Barnes & Noble databases,  I have found
only one book specifically on assertiveness that is aimed primarily at
men.

No More Mr Nice Guy, by Robert Glover
ISBN: 0762415339, Hardcover, 192pp
2003, Running Press Book Publishers
“This book is for all you nice guys out there who don't think you're
getting what you deserve out of love and life! Based on his own
experience of recovery from the "Nice Guy Syndrome" and working with
countless men and couples for more than 20 years, psychotherapist Dr.
Robert Glover presents you with a program of recovery that could be
one of the greatest gifts you could give yourself and your loved
ones.”
Available from Barnes and Noble for $13.56 as a hard copy, and for
$6.95 as an ebook in Microsoft Reader or Adobe Acrobat format.

This is a web site set up by Robert Glover to complement his book.  It
contains further information and the following free resources: Online
Support Group, Email Newsletter, Nice Guy Quiz (to find out if you are
one)

In addition, I found 
The Navigator Men's Development Workbook
James Traeger, Jenny Daisley and Liz Willis
Hawthorn Press UK 1999. Paperback. ISBN 1-869-890-80-9.
“The Navigator Men's Development Workbook is one of the very first
personal and professional development workbooks specifically written
for all men at work, on their own or in relationships and as fathers
and as sons…. Contents include: Realistic self-assessment, Challenging
expectations, A man's world, Clarifying values, Taking risks and
making changes, Physical and feelings fitness, Setting a goal strategy
that works, Assertiveness for men, Putting yourself across.”
This is a workbook used within a development course for men in the UK,
however, it can also be bought separately.
The publishers ask potential buyers to contact them direct at
hawthornpress@hawthornpress.com because they have various distributors
in difference countries.

I hope this answer is satisfactory. Please do not hesitate to ask for
further clarification.

Wow! There's certainly gonna be demand for such a book, if anyone ever
writes one. There are lots for women. Perhaps if you read one of the
female ones, nobody would pick up that you were acting like an
assertive woman, instead of an assertive guy. Then again, perhaps
they'd think there was something about you, they can't quite put their
finger on, that just isn't right...

It seems to me that the absence of such books is because most men need
to learn to rein in their assertiveness so that they won't go around
punching people in the snoot. ;)
