It depends on what I want from my orgasm...
I have been accused of being "moody" and I suppose that applies as much to my varying needs, my different levels of sexual desire.
Sometimes I just need to relieve a little tension and I may not have access to a toy, (I don't keep one in my purse at work anymore) so my hand does fine as a means of simple, quick, (it doesn't take me that long) short term relief.
Sometimes I need something more intense, more of a full release, and if the opportunity presents itself, (I have a toy, a vibe, in my car) I use it, most recently in a shopping mall garage in Houston. (Yes, the though of being watched is a HUGE turn on). The orgasms I get with a large vibe are more intense and leave me feeling more relaxed and satisified, and closer to feeling sated.
In bed, especially with a partner, I have been using a combination of dildo and vibe. (dildo in my rear, vibe in my pussy and on my clit)
mmmmmyesss....
The best is a tongue or a real cock though... maybe with a toy...
