Tickle wrestling; If only Gordon Solie had known.
Non-Bondage Tickling is great. A lot of posts here have indicated a presupposed need for combative force.
No.
It works like this...
HE: <I>Can I tickle you on the floor ?</I>
SHE: <I>Sure, Ok.</I>
She lies on the floor and extends her arms outstretched above her head while still lying them flat on the floor. He places his body weight on his knees and feet, which are positioned on the outsides of her arms, making sure that no part of his weight is pressing on her. His lower legs gently tuck her arms underneath his body, while not placing any pressure on her at all. Light and gentle tickling then begins over any different part (and preferably all) of her torso.
This also provides an excellent opportunity for (shameless plug) conversational tickling (see profile for E-mail address, hint hint)
And finally, one other big thing about simple cooperative non-bondage tickling like this; remembering to thank your 'Lee (or 'Ler) for the tickling opportunity and the tickling time together can do wonders for the psychology of the man/woman relationship.
