definitely dominant (warning - explicit!)
I am definitely a dominant, and when we have time, tying and tickling is part of our best sex...
For example -
A couple weeks ago, I tied my girlfriend's ankles together to the footboard, and tied her big toes together (also attached to the footboard). I am a foot bondage fanatic as well as a tickling fanatic. Her hands were not tied but she could not move her feet at all or stop me from tickling her feet.
After a lot of tickling and erotic teasing, she was horny enough to explode (without me touching her crotch, breasts, etc. at all).
After I untied her, we had a massive and lengthy sex session (about an hour of hot and sweaty intercourse - I do not exaggerate).
However, we are so busy, this is unfortunately the exception, not the rule.
